DP had a flaccid penis whilst I was giving him oral.
Strangly, I could hear he was close to orgasm, so kept going. During his moaning, his penis became a semi.
As he ejaculated, and in the moments after, his semi turned into a full erection.
In my 30+ years of having sex, this has never happened to me.
I've been with DP 18 months, and ED is a very common occurrence, hence why I was happy giving oral on a flaccid penis. He's told me he still enjoys it.
So what on earth happened? Why did the erection come after the ejaculation? I've never heard of this or experienced it.
