I don't know if you want a virgin seme x experienced uke dynamic or if you're also okay with virgin seme x virgin uke dynamic.
Anyway, since you said virgin seme:
↓↓↓↓↓↓↓↓↓
Dreaming of the dokkaebi
Sketch
Hit me Hard
Frey! (seme turned uke for first time)
My way with you (seme turned uke for first time)
Respect for taste (seme turned uke for first time)
You are so Lovely (idk whether the uke is experienced or not, i don't think he is though?, it's a "raise your lover trope)
↑↑↑↑↑↑↑
These all have virgin seme with experienced ukes.
For virgin seme x virgin uke →(you can check out my list "both virgins(BL)" i have the descriptions written for most of them and add a crybaby/pupper seme caption if there is one. But still, on top of my head, I can remember few of them. (I love virgin4virgin trope so I kind of reread the stories haha)
Love Plan (crybaby with seperation anxiety seme)
Red String Quests
High Clear
Off track crush
So, who got screwed?
The best luck of my life
Home
Cottage garden (pupper seme)
Die if you aren't a virgin!
I love virgin4virgin of you know any recs with v4v and buff bottoms do tell me!!
Okay some more crybaby seme virgins I remembered:
Romantic Captain Darling
Golden Pair (age gap as well)
PS. I have not read the virgin seme x experienced uke pair, (except "My way with you")
It's personality choice as I DO NOT enjoy a virgin x experienced dynamic (except some exceptions...) but these are the comics I know bc I DROPPED them bc of this reason.

i js finished despite that n it awakened the beast in me that yearns for adorable/virgin/submissive semes...if they cry too its even better! pls does anybody have any good bl manhwa reccs for that???
