I will give my opinion, but let me make a couple of points first:

I don't think it's a good idea to have sex with multiple people before you marry or commit to a life with someone.
A relationship does not have to include sex.
It is possible to be attracted to someone with no sexual intentions.

Now, you said the only time you have had sex you were more or less raped? I can see that turning you off men. But you have not really had a loving relationship with a man or woman. I understand being attracted to one or the other, but how does a person know they like the sex if they haven't done it?

I would advise you to not be worried about your orientation right now. You should spend time with both sexes as friends first, which should be done with any relationship. If you see things developing beyond friendship, then you might give more thought to what you want.

You sound pretty mature and level headed.
