Quite similar stories. One MC has had a crush on his straight bestie for 20+ years and the two of them become closer than expected after the bestie's divorce. Even tho the MC loves his bestie and the bestie agrees to be his partner, the MC refuses bc he's afraid that if they have sex, his bestie wouldn't be able to get it up for him
