witout enough info its hard to give a honest answer to you why do you think you need to experiment with same sex ?
Are you attracted to men?
Is their something that you want that your not getting in hetro-sex
anyways there are a lot of nice people here that will give you honest answers to your questions (you have to ask the right ones though)

I wouldn't consider myself attracted to men, but erect penises turn me on, and I've had fantasies about giving oral, receiving anal.
