I am having some problems with my boyfriend at the moment and would like your advice. We have always had quite a good sex life but there is one issue that bugs me. If I don't feel like it for some reason or it's that time of the month for me he hates it. He moans constantly and keeps on at me and says that we never do it!

A guys hormones are usually pretty regular, usually having an upsurge once a week.  Women on the other hand have hormonal cycles of close to one month.  This kind of creates a conflict because in the other three weeks your guy wants sex and you maybe don't have the immense urge to have sex until that time in your cycle when your urge is high.  Particularly women tend to have a point in their cycle where they really can't stand having sex.  For a guy that doesn't understand what it's like to be a woman and doesn't know much about how a woman's body works, it's like his girlfriend is being frigid or not pandering to his wishes.  To an understanding man, he should understand that women have times when they are not comfortable with sex and they should respect that.  When you have a bad boyfriend he will make you feel guilty and as if you going to lose him because of your lack of sex.  He's probably been gullable and listened to his friends telling him that they have sex a hundred times a week with their girlfriends.

If you demonstrate you don't want it, then to me that means that you are not really looking forward to it that much.  Yes, you do get times when you don't feel like it, but really if the sex was that good it would encourage you to want sex most of the time.  So really you have got to ask yourself is he really exciting you enough to make you want to have sex or is he proving sub-standard performance or even having sex at times that are just too predicatable which kind of makes it a bit boring. 

This is rubbish, it's at least once a week and I say go and sort yourself out if you want it that much.

Not really a good idea because that encourages him to find a prostitute or another woman, which is bad news for you if you really want to stay with him.  He is always going to exaggerate to get his own way and make you feel guilty.

He says that he hasn't maturbated for years and gives me the expression 'why have a dog and bark yourself'. Why does he feel he has to constantly rely on me for his sexual needs?

Because he has been able to rely on you up until now to provide him with those sexual needs, now you are not giving it to him, he is spitting his dummy out. 

I know it's important in a relationship but honestly Sam it's not like he never gets it. This is starting to become a major issue for me now and I am beginning to feel like a sex object.

If that's how you feel, then I think you should take notice of those feelings.  It sounds like it's turning into a one sided relationship where you must give him what he wants and you are not even considered or given what you want.  I don't know what your needs are from the relationship but maybe you should start telling him that if you fulfill my needs, I will more inclined to fufill yours.  If that doesn't work then maybe you should be looking for a better more understanding man to be in a relationship because maybe he is just using you as his sexual toy and not giving anything back. 

He tells me that other couples are doing it more than us and he feels hes missing out.  Why is he like this?

Ah, I predicted that above, he is comparing you to all the others that brag and exaggerate about their relationships.  Trying to make you feel guilty and push you into having sex with him. I have also got to put a blokes point across here though as well, guys hormones do get seriously high and the urge to have sex really is just too tempting, so I can understand why he really, really wants to get his sex.  But for the sake of one week a month, I think a guy should be more understanding with his partner and would also ask his partner whether she would enjoy doing something different sexually, because in the back of my mind would be that she isn't enjoying sex that much and there must be a reason for that.

I keep telling him that if he stopped pressuring me all the time I may feel more like doing it but he won't stop. He has even resorted to saying that he will look elsewhere for it if I don't do it more often. As you can imagine this makes me feels like doing it even less! He is good in other ways, I go to college and he is happy to provide for me and he does a lot of housework, cooks his own meals etc but this issue us coming between us. He also dislikes me spending time with my college friends. Even though he is at work all day he asks why I go to town or for a drink with my friends, or even stay at college to do assignments. If my friends come to the house he sits upstairs and plays on the xbox. If I go out with them he will cause a row when I get home.I am tempted to leave when I finish college because of these things thats how bad it has got. We go out ourselves quite regularly but if we are at home together we rarely communicate much and do our own seperate things. (I have tried talking but he isn't very responsive) Why is he being like this? !  Is he trying to control me?

Overall it seems as though he does provide some positive things to your relationship.  But by the fact that you say you rarely communicate with each other, that is worrying.  Because to me that is not a relationship, it is basically some people co-habiting and having sex.  Yes, he is trying to get control of you, he is probably wondering whether you going out with your friends and getting some sex elsewhere or even that you are trying to find an alternative man because you are bored with him, and quite frankly if you not talking anyway you should be getting bored with him and looking for someone else. 

This controlling thing can be displayed in relationships where the partner doesn't want to lose you.  But it can also be displayed in relationships where a guy wants a woman for the sake of being his sexual slave and pandering to his every needs.  As he does the cooking and housework and supports your college work I doubt that is the overall reason.  But it is worrying that you say that you don't communicate with each other.  To me that is not a relationship and means that you are not really got any potential for a long term relationship.  The only chance of a long term relationship is if you can sort it out calmly and get yourself communicating with each other.  Maybe then you can sort out your differences with sex as well.  I think he sees your relaltionship is going down hill and thinks if you provide him with sex that will make things alright, so I think really he has got other issues as well as the sex.  A guy has a need for regular sex, a woman has a need for sex but also companionship.  Neither of you seem to be providing the other with the right combination, which suggests that in the long term you may not be compatible unless you can sort out those issues.
