dineshsingh.. who is this HER, and wife that you speak of. The Original Poster only mentions his constant erections, nothing else. Am I missing something =/
To the Original Poster, how old are you? If you are anywhere at all during the ages in which a male hits puberty up to early 20s (when the hormones stop raging), there is nothing unusual about getting random erections. Unless you are having an erection for hours straight.
Heck, I remember during the many times I slept in high school, I'd wake up with an erection in class at the sound of the bell and wonder how was I going to walk properly and hide the erection.
That might have been too much info.
Point is, if you are having erections randomly (for short durations) between lets say age 7 and 24, no big deal.
