Lapdance ejaculation

I have had multiple times that I have ejaculated during a lapdance. Having a pretty virtually naked lady grinding on me is too much to handle and I cum. It's embarrassing to cum in your pants, I didn't let on that I ejaculated, but I am pretty sure the dancers knew I blew my load. Anybody else experience this? I'd love to hear about it. I don't think the dancers really like it, they must be disgusted by a premature ejaculation loser cumming in his pants! Leaving with a wet spot on your pants is humiliating.
