I wasn't doing anything else, no, but I do tend to have sex on the brain when I dream.

It wouldn't surprise me if this was a woman only thing. Women can use kegels to kinda kickstart their orgasm earlier (and make it stronger) during sex/masturbation, and they generally feel good to do if you're in the slightest aroused to begin with. To the best of my knowledge this doesn't apply to men?

Worked again for me, btw.
