When anybody wants to have sex they usually take off their clothes, but sometimes they leave their clothes on, and I find hentai where the characters have sex like that to be pretty sexy. Which do you prefer?
Can't and won't decide. Too many factors can change my preference for it. For example, I'm not gonna go full nude if I'm having a quickie somewhere public.
I really like this clothed sex genre.
I like it more Dressed-up than naked, but some parts should be exposed.
e.g. when they tear her pants instead of pulling it off
It really depends on the situation at hand, but as personal preference i'd find no clothing the most sensual, just the idea that you're both in your most vulnerable form and you're letting each other get that close and personal with one another, everything's there.
Having clothing like stockings and suspenders on however can really heighten the mood! c:
A mix of option two and three. It's like an extra element to add spice into the sex or even add a story line.
I suppose it's more of a mental thing but a little something on is just sexier.
