My wife and I are late starters to pot. She was doing some for months before realized it. I couldn't believe how horny I got when I found out. Then, watching her light her one hitter the first time and get high in front of me got me as hard as I've been in a long time. Good sex that day!
Getting high is fine for masturbation but I've always found a few drinks to be better for me. Both seem to have the characteristic of longer lasting masturbation and sex. So I prefer one, but I'm good with both...
It always did and still does make me extremely hard, it also seemed to help me last as long as I wanted.
