I don't know if I'm weird, but I don't like any of the three options.
The first, if it's with the MC, we should have the opportunity to choose to avoid it, and if it's with an unknown guy, we should have the opportunity to choose not to see it, I would choose avoid/not see it.
The second seems like a horrible option to me: all sex with a slut LI should be avoidable. In fact, any romance with a slut LI should be avoidable. I don't want my MC to have a romance with a slut LI. The truth is that I will never consider a slut LI as a real LI.
Regarding the third option, the only dream sex scenes that I like are those that can be avoided, because I avoid them and I don't see them.
