The look of a cut/uncut penis is subjective to each individual. Some think a cut penis looks better, some think ucut looks better. Cleaner? Cut or uncut it is still subject to daily hygene like any other body part.
Getting cut is a bigger decision than getting a tattoo, peircing, or plastic surgery for vainity. It affective a very curcial part of your life. I'm not saying that the wrong choice here is going to ruin the rest of your life. Unless something goes horribly wrong with the proceedure, it won't. Just realize that life after getting cut is going to PHYSICALLY FEEL different. Masturbation will feel different and you will have to adjust your technique. Sex will be different, too. It usually will take more stimulation/friction to get off, which may good or bad. You will loose that gliding effect you feel as your foreskin roles over your head as you thrust in and out of your partner.
I had to get cut at age 30. For me sex was better with a foreskin. Some may disagree, some may not. If you are happy with the way your sex life feels now why take the risk? The foreskin is full of nerves that give pleasure when stimulated, and it keep the head more sensitive, Removing the foreskin may make absolutely no difference other than appearance and appease you choice of stlye. Or, it could improve or lessen your level of pleasure.
You ask foir advice. Here is mine, finally. Don't do it. From my experience cut men are no cleaner than uncut. It is easier to masturbate with a foreskin, and it is easier to masturbate another man who is uncut. After getting cut it was more difficult for me to cum for oral sex. I have found it to be more difficult to get most cut guys to cum from oral sex as opposed to guys who are uncut. I REALLY miss that extra stimulation the foreskin gives as it slides back and forth over the head as you slide in and out of a partner.
Just think long and hard before you do because once you get cut there is no going back! It is not a peircing you can take out or a tattoo you can cover up.
