"If the amount of pleasure you get from sex is low or even negative, then sex may not be worth it, just as the risk of climbing Mount Everest would be too high if you loathe mountains."
This. Plenty of people do horse-riding which is a very dangerous sport. Horse-riders end up dead or paralysed by it on a regular basis. But for horsey people, being around horses is a big part of what makes life worthwhile. Not much point in somebody who doesn't like horses coming round to tell them that they should take up crochet instead because the risk isn't worth it. It's not about whether they're "generally risk averse"; it's about what makes their lives interesting and enjoyable.
Good sex isn't about what you ought to enjoy, it is about what you de facto do enjoy, what turns you on, what you get excited about. For me, that could never be either oral or anal for physical/phobia reasons which have nothing to do with sex per se (nothing to do with oldfashioned prudery or morality). Besides, the thought simply doesn't turn me on.
Random sexual encounters, as recommended by the OP and Crook, also wouldn't do it, not for moral reasons, but simply because I don't find the thought exciting. I see no point in sex, beyond the purely reproductive, if you don't actually find it exciting. Having oral sex with a random stranger because it was supposedly more wholesome, I'd be in the situation of some poor Victorian woman lying back and thinking of Britain.
