I am currently going to a physiotherapist. Seems like my pelvic floor muscles are very tight. She gives me shock therapy which loosens the muscles at the end of the session but in the next session they are tight again.

This is affecting my sex life because pelvic floor is reducing the strength of my erections. When I am getting an erection I feel pressure on either the top or the bottom part of the penis. The erections are soft and dont last very long.

Last time I talked to the urologist she told me that there is a medicine she can prescribe but its not a permanent solution. She said a side effect of the medicine is that I will get dry orgasms and cum will come out when I pee.

Are there any medicines that give a permanent solution to loosen these muscles?

EDIT: To be clear I am looking for medicines to loosen the pelvic floor muscle. Not painkillers
