Please help.A new hell opened up..i dont understand this now

M34 I have been dealing with hypertonic.pelvic.floor...from 1.5 year...it ranged from.constipation..to numbness...weak urine flow etc etc...eventually abstaining from.masturbation and some laxative..loosened the muscles....i researched and googled alot...i joined this forum..learned about reverse kegels..strecthing..and all other stuff...over time i made peace with what i had.Some positive posts..made me hopeful....

Recently,I joined a job..3 months back...since i had to travel a lot..i bought a bike...now my bike had tight seat...and it used to push my pelvic floor below my scrotum alot..i modified cushioning...tried to take some break and use car...life was pretty ok...although i still suffered....on and off

I recently made a gf...so we decided to have some fun virtually..and about 15 days back...i jerked off 3 times in one night....normally i would suffer some constipation...i would abstain and get better in a few days...

But this time...muscle just below my scrotum..fells tight..when i end..urination..i feel a sting at the end....this feeling is not going away...i am feeling irritaion..nerve like...below my scrotum and between my anus...and relaxation exercises..and streching..is only helping tempirarily...when i get hard....irritation comes back...

Now i am totally crushed...i just cant win with this pelvic floor thing...just when you think...you can manage your life somehow...a new hell breaks loose...i am unable to totally abstinate from masturbation due to immense lonliness and frustration in my life....i feel like giving up...please..tell me..if anybody has these symptoms..how should i recover?is it even.possible or i have pushed my muscle irreversibly?

And btw..i saw many doctors..they dont think this condition exists for men...one of the urologist made fun of me too..i have weak erection problem also ... Anybody please???
