Ok I know one that has VERY intense tension, but intimacy happens early on BUT the tension is so heavy and I genuinely love it also I will try to find some more bc I think tension/development is what I'm missing
WALK ON WATER
1995 YOUTH(I think)
Bt dubs there will be more to come and their both Bls, I don't read a lot of Gls

( It's ongoing they haven't done it yet)

(Very clingy, sex after marriage but shonen ai though)

Looking for GL/BL where the two have insane chemistry but they don’t fuck or get super intimate until basically the end when all the tension is built up. Sick of reading straight up pornhwas all the time TYYYY
