No, not an ad; a question.
This is impossible to Google due to the overwhelming junk that a search yields. So, maybe the experienced hobbyists here can offer some real advice. I remember when I was young, being able to get some air-time with my cum shot. But, it's been years - probably decade(s). Now, more of an ooze. It still feels good (wouldn't be in the hobby if it didn't) but I think a little more force would be pleasant. A little more volume also sounds good.
It seems kegels are supposed to help. Any endorsement?
Nutritional supplements? I'm suspicious of anything socially formulated and overpriced.
Perhaps technique, like edging?
