The first erection of the day is fine, no problems but then after ejaculation, if i get another erection with a few hours (sometime as long as 5-6 hrr after) my penis aches. i would not describe this as pain, more of an ache, and it is not localised to any part of the penis, jst a general ache. the thing is though that i have expereinced this problem litterally as long as i can remember (since i was at least 12-13 yrs old). when erect my penis is stiff, could this have something to do with this, i would appreciate it if you could shed some light on the matter. Thanks
