My workout routines for today

a) Warm up 10 mins
b) stretching ( helicopter shakes, stretch to left & right, circle stretches, kegel)
c) wet jelqs 60reps
d) V jelqs 40reps
e) Edging 25mins
f) Warming down 5 mins

Since i'm uncut. I have a sensitive dick. Nearly cum when edging but I manage to control my PONR today.

I have questions to ask hope someone can answer.
What does a dry orgasm feel like?
Is it necessary for men to masturbate every week. Does masturbation means that one need to ejaculate? bcs from what i heard 'ejaculating is bad for health'/ It may cause baldness?
How often should we ejaculate?
