i was diagnosed with a sciatic nerve problem after 37 years of age.  Since then, my list of ailments is as follows, problems with my left leg going numb, loss of feeling in my testicles and penis (periodically) my left arm went numb (like pins and needles asleep) for 6 months, it turns out my left leg is a quarter of an inch longer than my right, I have trouble with unrination flow (sometimes) and ejactation is not always strong.  I discovered all of this while receiving a blowjob, one of mans favorite joys, I orgasamed, or so I thought I did, and the female asked me did I cum, I thought that was odd, when I sat up (feet over the bed) something must have shifted and or opened up, and sperm  and precum flowed out freely, AFTER having felt the orgasam itself!  I was scared sh*tless, since then, I can't have sex in certain positions because if I don't feel it just right, my penis will go limp (mid sex) it's f*****g misserable, as it creates low self esteem, and the girl looks at you like poor baby.  And not to boast, but I used to have sex, two, three times a day, a few days a week (always with my partner of course), but if the wind blew or sheets rustled the right way I would get effect!!  I went to a urologist, he handed me a script for viagra and said that will get Mr. Happy back in the game, it didn't!!  There has to be a block somewhere because now, it does what it wants when it wants.  I get that as we get older the member isn't what it used to be, but this is something different.  I don't take meds, I work out, I do exercise, run, walk, don't sit long periods.  I thought it was BPH or enlarged prostate. The doc rammed two fingers in my rectum and said he felt nothing, I had a blockage in my colon, went to have an endoscopy, again, nothing out of the ordinary.  I will tell you this much, I have smoked some weed and that seems to relax everything and suddenly I have a very stiff errection, but truth be told I don't want to have "stoned" sex all the time.  I just want my penis fixed!!  Help
