bi, lesbian or straight?

So I have sexual attractions mostly to females (men can get me off too, but mostly girls) but I have romantic feelings only for guys? And, I want to experience sex but 1. The only guy to show any physical interest or any interest was a pig and 2. I never meet any girls who I'm close enough to do that with. And yeah, most of my friends swing both ways but all of them are with someone and also I wouldn't know how to ask them to give me that experience or whether they would want to anyway. So advice? On all counts?
