I agree with @Notthefordtype about how oral sex is waaaaaay better when you have shaved your minge. And it's nothing to do with 'the technique' or that man needing to learn how to do it properly. It was good with pubes, but OMG it's better without pubes. The sensations are completely different. You feel things yourself that you don't feel when you have a hairy box.
Also agree with @CaptainBrickbeard - since the advent of easy-to-get porn, men automatically expect anal sex, and many of the younger generation think it's a given that they have to do it. I have tried it a couple of times, and loathed it. When I told DH (after the second time) that I never wanted to do with it again, he was fine with it. We were both curious, and both wanted to try it, but I hated it. He said it was OK, but didn't care if he ever did it again. Like you captain I find it very hard to believe women really enjoy anal sex.
Agree with @Valanice1989 that FWB seems to benefit men a lot more than women, because most women in FWB situations like to believe (deep down) that their FWB secretly loves them, and they will waltz off into the sunset together like in a cheesy romcom. The reality is that it is very unlikely that this will happen. I bet you never get men on message forums asking if their female FWB really likes him and wants to get serious with him.
Men are just happy to get regular fucking with no commitment. Women may be to start with, but not long term ... (Whether they admit it or not, many women in these situations, want commitment, a lot more the than men do...)
