A guy like you is pretty popular , straight guys read it too , they pretty much liked the story plot .

As in he wants the smut?? Cos if yes then https://www.mangago.me/read-manga/sono_suki_honto/
If he wants to try shounen ai then https://www.mangago.me/read-manga/karasugaoka_don_t_be_shy/

Start with shounen ai? Some ppl think yaoi =BL, so maybe something without those parts are OK.
Try:

Salad days (slow paced, touching, more on subtle romance)

Southern Bird and Northern bird (link below, comedy, subtle, very cute, short chapters, main characters are two male birds)

Global examination (adapted from novel, action, I heard great things about it)

Black lotus( Dog blood, drama(the kind similar to ones asian aunties watch at home, but bl version))

“Shoulder to cry on” is great it’s slow burn shounen ai, one of them fights with accepting their sexual orientation and it’s overall great

thank you guys <333 very much appreciated
