Laughing at someone is hostile

As I made clear in another comment, that part was a joke. As in I didn’t mean it. I don’t endorse body shaming, even if someone’s a selfish lover lol

Parting ways amicably is much better.

Yeah, obviously.

I also think that men should not be pressed to do things they don’t want to do in bed

Nobody’s suggesting that. Can we do this without the strawmen, please?

Also, not every woman enjoys the same methods, so teaching a man something might not work for his next partner.

Sure, but some things work for more than one person. Such as being open to suggestions of how to improve. Which needs to be a two-way street and voluntary, of course.

People have different tastes in sexual stuff.

You don’t say?

It’s necessary to communicate and be prepared that there can be different preferences

Of course. That’s what I’m advocating for.

It’s ok if someone doesn’t want to do some stuff in bed.

Again, I never said to force anyone to do anything. I meant something along the lines of “X isn’t really working for me, could you try Y?” or “I really like X, is that something you’re into?”, NOT “do X or get out!”
