I agree with you. Im a guy, but i absolutely love dog cock. I like the way it looks, i like how it feels, i like how it gets hard, i like the knot, i like the taste. It just really gets me goin. I dont consider myself gay because of that, even though its a penis. For awhile i questioned my sexuality, thinking i was bisexual because of what i liked, but its not really gay in that sense.
Its a sexual act, yes. But being gay, in a traditional sense, would be becoming aroused and emotionally invested in someone of the same sex. I am absolutely turned off in every way by masculinity. I have considered going through trying to try a mans dick, but i just cant. I have even wagered with myself "well, if i got really drunk....i might try it." But i just cant. It does nothing for me, its not arousing to me, and there is no desire.
As you said, with a dog it is entirely different. It doesnt make or more acceptable for for a female to suck a dogs penis just becsuse its a female. This is not something that all women just. Its an different scenario in every way. I think its unfortunate that your boyfriend was so strongly against it, especially because you were willing to do something for him that was so taboo. Thats not ab easy thing to ask someone to do, but you did. I think you should continue to hint and push that youd love to see a man do it, and see if he will appease you.
Ive been in a situation before where my wife was sucking a dog solely because she knew i wanted her to, and after she had her fill of the experience, she handed me his penis and said "ok, now its your turn. Show me how much you like him." It was a very arousing situation and i was happy to give that back to her. After all, she did it for me. I didnt even get much time with him before she said "ok, well he tasted amazing, my turn again."
