haha, this is a little too based on RNG, tbh. Back when under the greenlight was airing (the top is a virgin while the bottom is very experienced both as a bottom and a top) there was quite a bit of them on the front page. I don't like either of those tropes, so I never ended up making a list.
But this one is a pretty recent one that I read -> https://www.mangago.zone/read-manga/ipsae_s_leaf_in_haneum_s_breeze/
https://www.mangago.zone/read-manga/a_room_without_space_side_story_1/ This one is more heavily implied but the premise is more apocalyptic world than relationships.

https://www.mangago.zone/read-manga/never_good_enough/ Not sure if I can call the bottom promiscuous, tbh. The top is a virgin though and the bottom is more experienced.

I can probably find out a lot more if I dig through my list but not sure if I am passionate enough to wade through hundreds of pages for them lol. There are a lot more with experienced bottoms with inexperienced tops but the bottoms aren't *promiscuous* and do not really fit into that trope.
The way this bl was drawn each panel feels like a movie scene
