last month i got the normal erection and i masturbate , after 2 days i got pain in my penis , then a drop of blood came after urinating , i got pain for 2 days . then there is no pain , after a week i got pain in the lower part of the penis , i got some stomach pain too , i got pain in left testis for 2 days , not continuous pain . now its bee month my penis is not erecting normal , i dont feel anything in the tip of the penis , i cant masturbate , but my penis is erecting when i sleep ... i got couple of ejaculation during sleep . i am afraid that is this a erectile dysfunction , or some other problem . or it will be cured by itself , i dont feel anything in the tip of the penis ,,, i am afraid too much . in the mean while i have took oflacin suggested by a physician , he thought it may be UTI . but my penis is not erecting now .... i never had sex ....
