surfsunbeach saidbut recently someone ive been seeing wanted me to grow it because its more manly. but ive got overgrowth, like thick pube tufts growing up the stalk of my penis and i think with more hair down hair, its getting smellier than normal too..
If you have a sex partner who's asking you to grow hair, and performs oral sex on you, their opinion might change if they start to gag on all that hair. So you do a "lover's trim."
Shave your balls completely (or use that cream if you say you like it), and also keep your shaft hairless. Only retain the triangle on your lower belly, which you might trim a little shorter if it's really bushy, especially at the base of your dick.
And unless the patch is really large, I wouldn't try to shape it smaller. That usually looks a bit obvious & vain on a man, whereas just making the balls & shaft smooth and retaining most of the rest can look so natural no one would know you trim at all. Which should please your lover's eyes, as well as the mouth. Just beware of stubble if you use a blade and have coarse hair.
I hope you don't mean shave balls with a razor. That sounds frightening. I don't want to end up castrating myself.
You should hold the skin taut, and I've found shaving in a warm shower or bath works best. I use ordinary Dove brand soap (in the US), not shaving cream, but I'm sure shaving cream is even better, I'm just cheap.
You use a feather touch, not like you do on your face. Another option is to get a woman's body razor, which I believe has a slightly different blade angle for fewer nicks. Perhaps my imagination, but a woman's razor does seem better to me than a man's razor for this job.
A final suggestion is a water-proof electric shaver intended for manscaping. Noreleco makes one called the Bodygroom, available in the US and world markets. Their online demos are funny (I think toned-down for the US market, I'm told some others are quite hot), which make very clear this device is meant to be used on your "bonsai" as they inexplicably call it, besides trimming back & chest hair.http://www.usa.philips.com/c/mens-grooming/18665/cat/
From this link you must separately click "BONSAI" then start the video you'll find, you may find it funny.
