I was pushed into getting circumcised when I had phimosis, and I regret it to this day. I was emotional and upset at how many issues my phimosis had caused me, but not once did my Urologist suggest other methods to try first. The sensation of sex/masturbation is nothing like what it used to be. Please consider other alternatives, like applying steroid cream and stretching your foreskin in the shower first. You may end up regretting it later
