Okay, I finally started measuring with the ruler pressed against the skin rather than just touching it, and HOORAY, I gained a half an inch!
I have two questions that may have already been answered, but when I search, I didn’t find any clear results.
1) The effects of caffeine on erection strength and length, what are they?
2) Last night, I was wet jelqing and I got up for a second to readjust my pillow. I was on my knees and squatting a little bit, when I lied back down I got a really stiff erection that wouldn’t go away for like three minutes. Did that posture I was in briefly have some sort of effect on my PC muscles or the blood flow or something?
