Can't maintain erection w/o PC muscles
This is my first thread on this site, so hello to everyone! Basically my concern is that when I am masturbating or with a girl, I cannot maintain a hard erection without flexing my PC muscles. I also used to have a habit of flexing my legs to give me a stronger erection + ejaculate. So about a year ago I decided to cut those two habits and just relax everything. But by doing this, I find I cannot maintain a hard erection unless I do one or the other.
One factor that might be telling of what my issue is: I have a difficult time maintaining an erection without constant touch. (ED? Too much porn?)
I think one should be able to have the whole body relaxed and still be able to get an erection hard enough for sex. But for me, I need to either tense my legs (which I don't really do anymore) or really flex and hold my PC muscles (which I do with a girl or else I cannot perform)
Any advice or similar stories + solutions?
