I love a smooth chap downstairs, I'm not a fan of pubic hair on men or women. A little decoration on the mons pubis is all good but anything on the actual penis or testicles itself is a major turn off for me.
It's been a good 8 years since I got frisky with a guy and found that he had hair 'down there'. It would be more of a surprise to me to find it there than to find none at all.
Waxing can be painful, but it lasts all of 10 seconds - and that's removing the whole lot. It's very very fast, so don't let the fear put you off. Afterward it feels warm, tingly and a little sore but this subsides within a couple of hours. I recommend booking some time to get it done, go straight home and sit around in the buff watching some TV while it calms down.
Some people have adverse reactions but most find that it feel relatively normal within a couple of hours. You can help it along by taking some paracetamol and popping some ice on the mons pubis and bikini line.
Regrowth can be made easier by using a body scrub on your mons pubis and testicles. It removes dead skin cells and prevents the folicles becoming blocked which will alleviate ingrown hairs - the source of itchiness during regrowth.
