(NSFW) Did I hurt his wiggle?

First time sleeping with someone is always a big question mark. Is it gonna go well? Will it suck? Does it being bad mean we aren’t meant to be, even though I like him so far? etc.
Well two days ago it was the first time sleeping with him, and I was on top, he got up quickly, went to the bathroom, came back after a bit and said “sorry, my penis I think you were twisting my penis…”

Now—- is this the truth, or did he have a premature ejaculation and hence made up a story for his mini escape?

I do not know. Any guesses? Haha!
