Yes, oral is disgusting. I kinda felt bad when my ex was trying to give me some once while we were together. Pretty sure we just kind of decided to not bother. Besides, plenty of other ways to do foreplay that don't involve mouths on each others crotches. I remember nibbling on her ear and suckling her breasts- they were very large and very sensitive.
I also wasn't really thrilled at the idea of a titjob, either, for similar reasons- it's not as exciting for the one giving it (even if hers were sensitive). And, in my opinion, the woman should be satisfied more readily, since I suspect they're less likely to be in many cases, instead of the men. I feel it's up to us guys to make sure the ladies have as good a time as they can.
Curious to note this is claiming there'd be absolutely no porn made for men, when we very much have porn made for women in the real world, even if it's uncommon. Not to mention the idea that men in this world wouldn't masturbate, when we totally have women enjoying themselves in the real world. There's even an entire sex toy industry built around masturbatory aids for women, primarily. Sure, men could use dildos or vibrators or such, but it's generally intended for female use. Gonna tell me a parallel world with reversed gender values about sex isn't gonna recognize male masturbation?
