There is no limit to what you can do really. It's up to the DM to build narrative around your decisions. If there is some character you want to try and bang, you can try to bang them. It is pretty much a rite of passage in any DnD game that someone has sex whilst all the other players sit around and sremoved at them laying on the moves. Lol at the auto-filter removing one of my words. That isn't a bad word you fools!

Play D&D long enough and you'll inevitably have a campaign that features some level of erotic roleplay, usually in orgy form.

You'll also learn why good DMs tend to just fade-to-black that sort of thing, because unless everyone playing is really into that sort of thing it's going to get cringey very quickly.
