Kegeling oneself into an erection.
This has been happening to me recently:
If I kegel really hard (squeeze tight and rapidly) I can sometimes get an erection. It only happens about 1/3 of the time, but still…wow.
Anyone else have this, or know the mechanism behind it?
If I could train myself to always get an erection on command that would be awesome. I think jelqing started this, or at least helps a lot.
