男人的快慢由什么决定

A hormone trigger. I'm enchanted with Jamie's restless desire ( stalk, mind-fuck his secret lover who's in copulation with a woman, leave in a flurry, but no, return and scrape against meadow and masturbate to put out that frenetic desire) and his violent jealousy (cut lover's throat when he's smiling to another man, like a whore, what a betrayal)
