Congratulations, Saint82 - the first dildo is a special one!!!
And no, you're not the first guy to go into an adult store and buy a dildo..... cos I done it three or four times!
And I can understand you wanting another already - I'm always on the look out for new vibe too!
Of course it doesn't make you gay! I'm bi, but not because I like sticking a vibe up my butt. Being gay is purely about being turned on by sex with guys. If you can't see yourself enjoying sucking a guy off, or getting fucked/fucking a guy, then you ain't gay, simple! And if you DO, well then so what? It's just a sexual preference, in the same way as liking big tits on a woman, or a shaved pussy or whatever.
And as for uses - well, if it's a vibe guys can also use it just on the tip of their cock, just like a girl using a vibe on her clit. And of course, penetration.
Now I agree with Sharni - are we gonna see some pics of this toy in action???
