As a guy and presuming the cis-het model, if a woman is swept up off her feet with simple "nice" guy rules, one should think hard and long about why.

Will her thirst blind her to anything, and that means when there are breaks in time with a relationship, will a nice guy sway her his way?

IF being nice leads to on-demand intimacy , under the pretense of dating versus "quickies", waht does it say about you being a community dick.

Personally, if I was single, I don't mind making sure my partner is well satisified; however, for intercourse where a child can be made?

No, I worked hard on my masculinity and me, so I expect the woman I am doing the dance with, to be a high quality and independent person "who" choose to be with me start to finish.

Taking the previous examples? She gets thirsty, her desire and the playfulness wants more, she will focus on me as I would focus on her when I am thirsty and away we go.

Enthusastic consent and couples privilege rules already documented and agreed too.

So if you think you are nice as a guy? I don't doubt your definition of nice is probably upheld 110%.

But That doesn't mean it fits your future partner's nice, which may mean nice = empathic + sympathetic + giving + human ....

Not just transactional.
