Personally I'm cut. And I'm just lucky to be able to say that at all because women in general (at least North American women) haven't got a clue how to properly clean an uncut baby boy.
Most women of a certain age were socialized not to be sexual or even sexually aware. The whole [banned word] on educating both men and women in the last 150 years regarding sex and sexuality has contributed to more medical and psycho-social issues in people than I care to think about but it is certainly one of the reasons that not only lead to the rise in circumcision in boys in North America because Mother's were never taught anything ... nothing about being a mother or a father for that matter - I'll say 'in the old days' to do the simplest of things like breast feeding and cleaning a baby's penis. With the incidence of mothers with babys in distress and pain over badly nfected dicks the standard practice of circumcision baby boys became the norm and some of us men of a certain age owe a debt of gratitude to this practice because we may have ended up with either horribly disfigured penises due to extreme infection or penile cancer as adults.
I for one was not circumcised at birth - my idiot father made that decision. I say idiot because 1. he didn't ask why the doctors wanted to do that 2. what was good for home should be good enough for me and 3. never consulted my mother to see if she had a issue with taking care of an uncircumcised baby. The results of his decision lead to my mother needing to be sedated and me to be given an emergency circumcision because my little guy was 3 time it's normal size and red as a barn door.
Having said all that sex education of both boys and girls in schools is improving and with the advent of prenatal classes for parents expecting a child, issues around penile hygiene of baby's, boys and men has vastly improved and the medical profession is now playing catch-up. Circumcision in most hospitals is now only performed when requested. Not all but madown and thankfully emergency circumcision rates are way down.
Do I like being circumcised ... since it's all I know I can't say one way or the other but I am glad to have my penis. The whole cut or uncut takes on a different perspective for me. I couldn't care less about if the man I have sex with is or isn't and I certainly wouldn't deny having sex with come one because of it as some of the men here have said; I truly think that is an insult that cuts (no pun intended) to the very heart of many men and I'm not that mean spirited or short sighted.
Do I have a preference? That really depends on context. Aesthetically, I like cut cocks on white men mostly because I'm a cut white man and it's what I'm used to seeing everyday and I find from an asthetic perspective the foreskin of a white man (not all but in my experience many) is less substantial ... it lacks gravitas. The cocks of men of colour who are cut in my opinion do not live up to their uncut brothers; again purely asthetic. Side by side photographically speaking I'd choose the uncut penis of colour every time.
Sexually, I love them all especially if they are thick and long. Cocksucking an uncut man is a huge turn on. There's more play with with and they feel every every swipe, swirl and flick of the tongue on their heads and as the cocksucker the moans are almost reward enough. But a cut cock is easier to suck especially if you like not using your hands and you've been asked or ordered by your partner to concentrate on the head and not to use your hands it's definitely an advantage to the bottom to have a top that is cut at least when your starting off. Practice make perfect but all things considered in those situations less energy is expended getting the foreskin out of way which leave more to focus on the head.
When I'm fucked I have no preference at all - size becomes the driver of enjoyment for me there. Cut men can last a bit longer but there's less clean up at the end ... and I do like clean up.
that my 2 cents worth.
