suddenly can't have an orgasm

  Lately I have been unable to achieve orgasm unless I really agressively masturbate.  I was doing keggel exercises for a while that I read in a mens fitness magazine, but only for a short time, now it feels like that muscle is so strong, my semen can not break through.  In fact I have noticed that my erection becomes somewhat flacid and soft before I am going to ***, prior to that it is rock solid.  My wife and I have a very active sex life and at times we are rather agressive and my penis has bent back where it feels like it pops at the base.  Should I see a doctor, all of a sudden it is so difficult to ***, sometimes it takes a hour.  Even though I only did the kegels for a short period of time, 20 a day for about a month, could I have done damage?  Hope you can help guide me.  Gratefully, John

Dear John,
If you feel that your penis has bent back and you did hear a pop, you may have what is called a fractured penis.  Usually, the penis will become limp immediately, and you will have some noticabl bruising and swelling.  This is a form of trauma to the penis and in 20% of cases it involves the urethra causing blood in the urine.  If there was significant scaring, and the nerves were involved,  the sensory nerves of the penis could be damaged making it more difficult for you to climax.
The definition of a fractured penis is rupture of the Tunica albuginia of the corpus cavernosum due to external trauma of the erect penis.  It usually occurs during vigorous intercourse as you described.  Basically, as the two tubes fill with blood during an erection, one of these is popped due to external trauma.
