for best results, sexual activities, love and commitment should go hand in hand

This is fine, I agree with it as written, but I dispute that "commitment" has very much to do with sexuality, except sort of tangentially, in that people are often bad at managing their feelings around it, or simply have extremely strong feelings which are hard to manage. It's true that if something affects you emotionally to the degree that it has negative impacts on your partner, you shouldn't do that thing, but that would apply to any stressful job where you took your stress out on your loved ones.

you shouldn't make money out of something so intimate and important as if it were nothing

This on the other hand is the kind of thing that religious people say when they don't want to admit that they see women (and let's be real, it's always women we're talking about) as property.

Of course you can date or not date anyone for whatever reason, nobody can make you. So indeed, the world is big enough for that.

admitting it is too much so you have to fight strawmen

This is exactly what you are doing with the second statement. If you were to honestly dissect why you think that "making money out of it" would mean that "it were nothing" you would be able to see that too. It implies that someone doing OF somehow lessens the commitment to their partner. Robbing him of something you see as rightfully his. It is this deeply engrained patriarchal mentality which is in the end responsible for most of the emotional issues.

And sure, if you can't handle it, that's ok, many people can't. We all have things that are hard for us. But it's better not to lie to yourself about where those feelings come from.
