I'm also someone who has developed an adult-onset phimosis which became visible 20-some years ago [I'm now 80.] when a cord of inelastic tissue, a phimotic ring, became evident. Today, little more than the meatus can be exposed. Whenever I'm hard, the tightness is so exquisite I'm able to cum hands-free!
the condition of phimosis is nothing to do with being gay, in my case i suspect that i have caused it to myself by a lifetime, about 60 years, of regular wanking. the phimocure kit that i bought offers a range of stretching rings to enable you to get rid go the tension in the end of the foreskin. look it up on the internet, you have nothing to lose.
