Urethral play | Urethral sounding and play to…

I've been on an SSRI for a short period of time to treat anxiety. The side effects haven't been too bad until I finally realized the worst one. I figured my libido wasn't affected since I'd been having erections, but the other day I finally realized what was truly different. I'd been preoccupied enough with daily functioning and trying to get a decent amount of sleep that I didn't have the drive to masturbate or have sex like I usually would. Then when I did try to masturbate, I was hard but couldn't cum after a lengthy session. The same with sex. After some intentional or unintentional abstinence, deep, hard anal sex after I enjoyed giving my partner several orgasms would normally end with a voluminous load in her ass. Not so. I had a rough case of blue balls and the majority of the aching was in my prostate. I finally relieved the aching and pressure using a 24 Fr/8 mm Pratt sound. I flicked it across my prostate as I gently stroked the the of my cock. When I climaxed, I pulled out the sound as quickly as comfortable and it was followed by a massive amount of semen. It must have been at least three tablespoons worth. I was very relieved by the experience and I'm wondering if others have had similar experiences with SSRIs with regard to delayed ejaculation which was resolved by internal penetration.
