I've been doing prone masturbation because I cannot cum the normal way. Is there a problem with me?

First of all there is no right or wrong way, so do what works for you. A few years ago there was a boy in my cabin at camp who could only cum by lying prone and humping his mattress. He could never bring himself to orgasm with his hands. If this is your preference you aren't alone so don't be concerned about it.

When you are prone you are probably getting some good pelvic motion that you may not be getting when using your hands. If you are lying on your back, try alternately straightening your legs and then bending your knees slightly, using your pelvis to thrust your penis into your hand (use some lube). It may work for you but if not don't worry about it and just use whatever method works best.

And just to add that if you are trying to switch from prone masturbation it will probably take some time and practice because you have been doing it that way for several years

I Need help quitting because it’s giving me depression and I cannot get a boner when I touch my penis only when watching porn

And I don’t have lube because I’m 15 and use Vaseline

It’s for trying to quit prone masturbation btw

Fine, use Vaseline. Take a few days or a week off so you get turned on, then try using Vaseline and your hand and get some pelvic motion going so you have some thrusting action

Would doing prone masturbation for 4 years lead to ED

I can still pre cum with my hand but not ejaculate

Have your balls dropped?You have big penis on hard?Can you can yet?

No it wouldn't lead to Erectile Dysfunction ,do you get turned on a lot?

Keep using your hand to jerk off ,do you masturbate to gay porn?

Your 15,masturbating and trying different positions is normal for 4 years you have done the prime postion,try masturbating in the shower,have your balls dropped ,have you got a big penis on hard?

Are you circumcised?How many times a day do you masturbate?Try massaging your balls cover your erect penis and balls you will cum better
