Need more info in order to give you a complete answer. I will assume that you mean after edging to the point of orgasm without ejaculation.
I wouldn’t say I lose the errection after each orgasm, but it goes from 100% to about 90%, still enough to have sex or continue edging easily.
If I’m edging in this way I can have about 5-10 orgasms, each orgasm 1-5 mins after the other, without ever losing the errection.
Edging like this is seriously good for prem ejac.
