Anyway, you are probably bi-sexual. Either way, it's fine. I have plenty of gay male friends and plenty that love girs and guys. If you love girls but enjoy doing this with your step-brother, then either you're in denial about being gay and you only think you like girls or your bi. You may not even be bi, you may just be "curious". The only thing sick about what you're doing is that it's with your brother.... step-brother or not, that's incest. That's why you probably feel weird because you know it's wrong. Try doing that shit with a male that's NOT related to you and see how you feel afterwards. If you don't feel weird then you probably are gay or bi. If you do feel weird, then you're obviously straight and may be going through and "experimental" phase which is perfectly normal. Alot of people fantasize or try thing with the same sex. Some like it and stick with it and some hate it and realize it's not for them and it's not what they want. Whatever you choose, remember it's perfectly ok what you prefer sexually - there is absolutely nothing wrong with being gay or bi-sexual and don't ever let anyone tell you differnt. Like I said, try with a different male with no relations to you and see how you feel afterwards and let me know. Good luck and let me know.
Forget for a minute that this is your brother/step brother, although that in itself is plain wierd. He's 12!!! That's far too young to be having sex, sucking your dick or whatever. And this has been going on for months??? If you were much older you'd probably get done for child molesting. If you're gay you're gay but find someone your own age to do it with.
I agree - it is fine to be gay or bisexual, but involving a 12 year old is reprehensible. I suggest you seek out kids your own age and stop doing anything else sexual with your step-brother. If you do not, and an adult finds out, you could very well be arrested.
i have the same problem!! like wen i get horny and start to masturbate after a while the pleasure gets to being too much and i regret it and do it agen the next day!! im even doing it rite now!! so dont worry your not alone!
