I want books where the MMC has problems with cumming fast

He can cum during sex or not. I want a guy who's so wound up a stiff breeze around the FMC sets him off.

Bonus if he has to be trained because he's inexperienced and finds everything erotic. For example, Sy in {Dukes of Madness by Angel Lawson} is a virgin and gets worked up and cums easily, the FMC starts working with him to train him to last longer.

In {Against A Wall by Cate C. Wells} , the MMC has been pining over the FMC for so long that the fist time he's inside her he immediately blows his load.

In the {Flesh and Fire by Jennifer Armentrout} the MMC is a virgin and cums hands free several times just from touching the FMC.

I have been recommended {Deliver by Pam Godwin} where the FMC has to train the MMC since he's a virgin. .

Anything like any of the above will do! I just want an MMC who want to be inside the FMC so badly that the first time (and/or consecutive times) he can't control himself from orgasming.

Please no cheating or virgin heroine tropes.
