Tight pelviv floor muscles

Hi
I hope everyone is good
I’m a young boy 19 years old. I have been masturbating since last 5 years . It has caused a lot of problems. I tried so hard to quit but I couldn’t. 48 days is the longest streak by me . Due to masturbation now I have verh tight pelvic floor muscles . These muscles are very tight (tensed) all of the time . Now I’m trying to relax them
First I didn’t know the difference between bc and pc muscles and I used to train bc muscles . From today , I start my 90 days challenge
Need your suggestions in relaxing pelvic muscles
Moreover, due to tight muscles , I don’t have hard erections and I can’t stand straight .
Thanks for reading
