I don't know why you would think that means he's gay. Women clearly turn him on. He has some kind of phobia about insertion.
maybe he watched Vagina dentata
His sister called him 3 cm when he was little. He has some insecure problems.
No no sexuality doesn't work like that lol Also your question would be valid IF he showed interest in the same sex... Because him going limp before insertion but totally adoring the opposite sex otherwise indicates that it's most likely psychological...He must have some phobia.
Hmmm
His dick goes limp at the thought of having it inside a vagina.. isn't he gay then? Or bisexual at least since he still find girls attractive..
Someone, throw me a bone here!
