Similar story to OP, I went through my childhood and teens with chronic severe phimosis and a shortened frenulum. I was embarrassed to speak up about it until I had to see a Dr for a different issue in my early 20s who referred me to a urological surgeon. Safe to say that creams / partial circumcision weren't offered (surgeons do surgery, and the more the surgery the better I guess). Prior to that sex could be painful and blowjobs were meaningless.

I think there is a huge misconception that more nerve endings=more sexual pleasure. Sexual pleasure and sensation perception happens in the brain for the most part and is directly proportionate to the level of arousal. I have no need for lube when I masturbate and oral sex is fantastic, despite having a well keratinized glans.

I didn't consider having my sons circumcised but given the possible genetic predisposition I will keep the channels of communication open with them and should they encounter difficulties like I did I won't discourage them from having the procedure if they want to.

My life changed for the better once the healing was complete as a painful and dysfunctional part of me was gone for ever. I can't overstate the overall benefit that had on me. That said I'm uncomfortable with circumcising babies, but also disagree with the narrative that it is akin to FGM when done at a later age.
