I like have sex with boys my age or older but I keep wanting to find a girl to see what it’s like. I think boys are sexy and I also think that a lot of girls are sexy. Am I a lesbian?

I think your problem is that you’re only getting half of the pleasure that comes from sex. Part of the pleasure comes from having orgasms, no doubt, but the other part comes from the intimacy of being with a loving partner. Since you seem to be having sex with many partners, and you’re only 17, I’m guessing that these are just friends, not real lovers. So because you’re not getting everything you could be getting from sex, you’re not completely satisfied and so are looking for ways to make sex more satisfying, leading you to consider what sex would be like with a female. You’re not a lesbian, you’re just not fulfilled by the sex you’re having. So my advice to you is to put aside sex for a while. You can masturbate, but don’t have sex with a man until you’ve found “the one.” Develop a relationship with a guy first (and by not having sex right away, you’ll both be able to discover whether you’re in love or in lust) and then see what happens. I bet that once you’re in a real relationship, you’ll find a lot more satisfaction and won’t be looking to push the envelope.
