depend on a couple . a couple can get weak to emotions or get full of emotion in sadness or hapiness which can lead to arousal and then sex. take an example when one of the couple is sad and they see that their partner is their for them they get emotional and also feel loved which can be exciting for some people .its not about crying actualyy its about feeling emotion and love from their partner which make them want to have sex

You mean single, right? I am also single. I understand that couples can be that way. Weird.
Is it normal between cuples that if one cry the other one will have sox with their lover.
Its always happen in mangas,its somehow not true for me
