Just a curious question of mine... I am not a bisexual myself, but I always have an enticing interest for taboo. When you give oral sex, which genitalia do you enjoy giving it to the best?
When I give oral I prefer it to be with another man, but when having penetrative sex I prefer it to be with a female - and that applies both for vaginal & anal sex. As for receiving oral sex, to be honest I can't say I've noticed any difference - after all, if you were blindfolded & not be told whether the person giving you oral, or even masturbating you, the chances are you wouldn't be able to tell the difference - it's all a matter of neuro-physical stimulation after all.
I love to please. That's what gets me off. So when I had girlfriends, I loved their pussy so good! and since I've found my mate, I love his cock like crazy! I get turned on just thinking about going down on him until he hits my tonsils... um, what was I saying? Oh, it totally depends on who I'm into at the moment, to answer the question.
