Talk to Sexologist on Hypersensitivity & PE

Hi i need advice I am about to get married in 3 months iA.

Due to excessive masturbation, i am feeling hypersensitivity, i left masturbation couple of months ago, but whenever i get errect i feel like i’ll get ejaculated due to hypersensitive penile. Whenever any pressure is applied on midshaft & proximal part of penile. I tried wearing condom too, but due to its tightness i get ejaculated.

Please please help, i am reducing my belly fat too, going to gym regularly. Anything that can help?

Additionally what tests should be taken care of before visiting any urologist
