I find i can't masturbate and have a normal orgasm. When i watch porn i need to hold myself back from cumming and really concentrate on giving myself a strong orgasm. I know how my body is tuned and i now know how to give myself a strong enough orgasm, and when i do it leaves me horny throughout the day and the days following.
If i was to have a half hearted orgasm from masturbation, i would feel a bit deflated and my libido would be a lot weaker. Maybe some guys aren't able to give themselves a strong orgasm through masturbation, which in turn leads to a lacking libido. I am sure guys here have higher libidos after they have a fantastic orgasm, right or wrong?
When i have sex, i have to edge for a while and hold back from orgasm and it's sometimes hard to get my girlfriend to do it properly, and if i cum too quick it really bothers me and afterwards i become uninterested in sex entirely. I think it's all about knowing your body and how someone can get you off, or how you get yourself off.
