besides a lot of girls enjoy looking at what man actually looks like. They dont seem to like excessive hair and they often get a kick out of shaved chests sometimes. But at the same time if you shave off every hair down there it might possibly invoke a comical reaction from the women. Its something they would definitely bring mind to others for better or worse as to them one would need an apparent reason to shave it all off unless they just so happen to like it. That or another girl made them do it.
" tee hee, Betty did you know that Donald likes to shave all his pubes off?" "why does he do that?" "Mary did you know that Donald likes to....."
" No, he just does it on his own, maybe he likes the way it looks, maybe sandra likes it that way, or maybe....."
Then your known as the guy who shaves his pubes off, seeing as how a major reason guys like to do it is it makes the johnson look less small and you dont necessarily want to imply something that isn't true
but like the other guy said the trends are changing I'm sure many people find it sexy these days.
You see its a whole social thing.
I know some girls must like it without hair or if its excessive they might ask you to at least shave it down a bit. It would be weird at first but in the end she'd get used to it or even desire it. but I dont have the most experience with that so who knows. maybe couples would have more sex if we all shaved down there anyway. To be honest I'm frightened as hell to do it.
A plus side is if you already have the hair you can always shave it upon request or as a suprise, something to living up her Wednesday evening. and if I know anything about relationships (which I dont) being asked to shave then doing so is a definite sign of commitment to making your partner happy. everytimes she see's shaved after that she will be reminded that you do it for her. Then when they do shave it they leave at least a little something remaining, they refer to it as landscaping, women are big on it themselves if Ive learned anything from the internet.
So besides the fear of blood in the worst spot and possible social tangling, there just aren't enough reasons out there for most guys (especially single) to shave themselves off unless they get a kick out of it or what themselves to look bigger.
