For as long as I can remember, the shaft of my penis and sometimes my balls have always ached whenever I get an erection within about 5 hours of ejaculating earlier. Is this normal, and has anyone who has had this problem found a way of preventing it? A possibly related problem is that the head is sometimes quite sensitive for up to 24 hours afterwards so that it can be a little uncomfortable walking!

The problem is worse if I have ejaculated on a number of consecutive days (i usually only ejaculate once per day at most, up to 3 days in a row because of these problems).

Any advice much appreciated, thanks!
