I think save is not the big issue. Good looking is important. If you are looking good in shave then clean shave is not needed. Just go to get girlfriend, not think much.
I guess its not about clean shave its about your personality and your way of talking to impress someone.
No they expect you to shave all your body hair off, best get removing that bum fluff that's been growing...
I really sincerely think it does not make any difference whatsoever. Some girls may prefer clean shaven while others may prefer scruffy. The important thing is that you be yourself and keep your face however you want regardless of women. Women are WAYYYYY more attracted to things like self confidence, eye contact, body language, saying the right things, being independent, etc. I don't think they really care about physical appearance too much. Women are attracted to a man who can take care of them, it is hard wired psychological thing and physical appearance doesn't matter too much. So, my advice is to just be yourself. If you choose to go with non-clean shaven, keep it clean and neat. Other than that, disregard the bullshit and have fun mate.
No man is clean shaven for long, as soon as he shaves the body works on replacing it. So really you're just fighting against nature and what it means to be a man, if you want to shave your penis off that's totally cool with me.
