Yes, you are gay. But does it matter? And why does this question have a -6 rating?

I don't believe it means your gay or bisexual. To be Gay or bisexual you can't just be attacted to the sexual act of being with the same sex. It goes much further beyond that.

you are bi.

It sounds to me like you are bisexual. Either that, or you just love anal sex.

It means ur bi. Like me :)

No, that doesn't make you gay at all. It makes you BI-SEXUAL.

Bi-sexual is when you are happy to have sex with either sex, male or female. Some say it is the best of both worlds, other people say it is wrong. I say who cares! Do what turns you on, do it safely, do it respectfully, and have fun and enjoy the experiences.

engaging in sexual activities with the same sex is gay

It all depends do you love the females, or do you love the males. Or do you love giving anal sex? Me i love females, I love receiving anal sex, but I don't love males. When i am having sex and a male is pounding my ass, i go into fantasy mood and picture that i am a female or a transgender female (ie-Kimber James). I prefer to have sex with female or tgirls over hunting soully males. And hopefully the males are shaving or little body hair too.

you are bisexual my friend, enjoy

No, not necessarily. All it really means is that you enjoy anal sex. If you are attracted to the men and not the women (ie. you only have sex with the women because no men are available) then probably you're gay. If vice versa, then you should probably consider yourself heterosexual- and in both cases you really need to consider whether its a good idea to be using people in that way.
I suspect its likely that you are bisexual to a greater or lesser degree, but with the little info I have to go on here, I'm not sure I can really be much help on that score. The truth is that sexuality really isn't a clear cut black and white issue. There is no set of boxes that you can tick which will identify you as being gay, straight or bisexual, there are many straight people who have had sexual experiences with people of the same sex but would never in a million years consider themselves gay (After all, is the schoolgirl who practises kissing with her friend a lesbian, or even bisexual, ten years later when she's happily married to a man?), and I know several gay men who's earlier sexual experiences were with women before they really "found" themselves- they still describe themselves as gay, as opposed to bisexual, as the term gay better represents their feelings. Its something you have to discern and figure out for yourself by exploring your own feelings for men, women and about yourself. Ultimately you yourself are the only one who can tell you whether you are gay or not.
