Urology/How hard


Im 20 and I dont get as hard as I used too. How hard or rigid do you have to be to have intercourse. Im not super stiff but my penis isnt bendy either. Is the only reason some people cant penetrate with a not hard erection because it flops?  This concern happened after I slept with a girl and in the morning i couldnt penetrate....but again ifeel like i should be hard enough


There is no easy way to describe the degree of hardness required.  If it's just barely rigid enough to penetrate, we arbitarily call that 50%.  At your age, it's almost certainly psychological.  Discuss this with your physician if it continues.
