Girls that don't know much may say they care, but they really don't. Women that know what it is all about are said to prefer natural. However, in the US most guys were cut, although that is changing.
Girls don't reject you (and will not laugh at you) because of the NATURAL state of your penis. I was born in the 60s and I am somehow natural (thanks MOM). Most boys were cut (although in college I was shocked that 3 out of 5 of my poker buddies said they were NATURAL). I had no issues. In fact in the late 70s when I dated in HS, I think hippie chicks thought that a natural guy was a real find, something special. In the 80s, I was surprised that women I dated for a short time and had sex with a condom on did not know I was natural. It looks the same erect and it feels the same to them with a condom on. With a condom off, they say it feels better. You are in a better situation as much fewer boys were cut in the last 14 years and the cut rate is falling like a stone. In NYC is under 50% for the time since at least the 50s.
Don't throw away the natural parts, you may want them. The foreskin is not just skin and does not just protect the glans(head). Circumcision is now known to ablate the most sensitive parts of the male genitals. This surgery takes away the main male pleasure zones with about 20000 fine touch and stretch nerve endings amputated. The foreskin has several parts including the ridged band that is great for ones pleasure (that is why nutters like Kellogg wanted to chop em off, to curtail masturbation), Masturbation is important for a mans physical and mental health. The ridged band directly contacts the vagina for very great pleasure all around. The dynamics of sex and the actual mechanism of the penis are drastically changed by circumcision. The foreskin can normally be slipped all the way, or almost all the way, back to the base of the penis, and also slipped forward beyond the glans. This wide range of motion is the mechanism by which the penis and the orgasmic triggers in the foreskin, frenulum, and glans are stimulated. The only touch organ possessing as rich erogenous innervation as the foreskin is the clitoris. Circumcision deprives man of 2/3ds of the main erogenous zone constituted of the foreskin and the glans.
