Iv been having casual sex with this bloke for 2months now, and recently iv noticed im starting to get emotionally attached. We have been on several dates and normally after these dates, end up back at his house having sex.

You are bound to get emotionally attached to someone you are having sex with and meeting up with regularly, it's almost natural.

This bloke is very attractive, but im starting to get concerned about his needs in bed. Im a very confident lady in the bedroom, but this man knows no limits! He enjoys anal sex, he enjoys using numerous toys on me and recently he asked me to pee on him!

If you don't enjoy that sort of thing you should tell him, them is no point in doing things you don't want to do.  True, it's possible that if you don't try something you won't whether you'll like it, but really you shouldn't be doing things you are uncomfortable doing, particularly sex wise.  Quite a few men will want to do more than a woman would be willing to do, it's just most men wouldn't dare ask for fear of losing their woman.  I certainly wouldn't try anal sex on a woman, unless she made it clear she wanted to try it.  You have got to wonder what you are going to be doing next, because once you've gone so far he will continue to keep pushing the barriers.

I was with my previous partner for 3 years and enjoyed our sex life, but my new man is completely filthy! I do enjoy having sex with my new bloke, but its starting to make me feel slight degraded and a little bit used. (I cant seem to say no! – when I say no, he usually gets his own way).

You have got attached to him, so one part of your brain will be telling you, you don't want to do these degrading things and the other part will be saying, if I don't I will lose him.  He has you hooked and probably thinks he can get away with doing anything.  If you find them degrading then you shouldn't be doing them and you need to tell him that.  If he suddenly dumps you for it, the you know he wasn't worth being with anyway.  You have a right to be happy and you can't be happy doing things you find degrading. 

What you should say to him, is that you don't mind being experimental sex wise, but you would prefer to stop doing the things you find degrading.  If he doesn't like it, he knows the way to the door, and if he doesn't like it, then it's best for you if he finds his way to the door.  Because you can't spend the rest of your life doing degrading things for him, he has to respect your needs.

My bloke has asked me what I expect from him, in the future. I have always made it clear It was always just a little fun, but the more time Im spending with him the more I want.

The more time, you spend with the more you will fall in love with him.  It is up to you to make a decision, do you want him for the rest of your life or not.  The fact that he is asking about your future, makes me suspect he might want a bit more than fun, to actually bring that up in conversation.  Or maybe he just doesn't want to hurt you and wants to make sure you are not getting too attached to him.  I can't really tell you that, it is up to you to extract that information from him, in whatever way you can.

After sex, we enjoy the cuddles and pillow talk, but im still confused!

That's good, he doesn't just shoot off after sex, he gives you some TLC.  But you have got to start to make a decision, do you see yourself spending the rest of your life with this guy, or is it just a bit of fun/a fling?

I want to no, how long can two single people have casual sex for?

Judging by some of my friends, it can continue for years.  But it is not really healthy for your long term future, if you are just having casual sex with someone.  Eventually you are going to be getting old, and want to settle down with someone, if you are having casual sex with someone, that is going to get in the way or you finding someone who is more long term.
