Japanese women are quite hot in my opinion.
When I lived there, one of the girls I had a major fling with had only had sex with 2 guys. One of them a college professor.
Neither guy had ever engaged in foreplay. Her opinion was that sex was a painful activity. She'd never had an orgasm. Just today my wife was talking about her mate that has a Japanese husband. She's now got a boyfriend 'cause hubby rarely gives it to her and when he does, he just puts it in for 3 minutes, comes and doesn't even consider whether she's done or now.
When we first started seeing each other, it took many attempts to go down on her. Sometimes I'd get close and she'd snap her legs together. One time I looked up at her, my head trapped between her legs and said
"Is there something fucking wrong with your legs?" I told her to just let me do this one time and I'd never try again. Well - that opened pandora's box didn't it. She turned into a total cock monster after that. I pity any Japanese guys that ended up with the very demanding Junko after that.
Jap porn is fucking weird - I don't think I've ever seen Jap porn where the girl wasn't squealing like a pig. The intent, I presume is to make it look like they are enjoying it too much - as if the guys have them overcome with pleasure. Then bondage, pissing and all sorts of oddness is mainstream there.
Kiddie porn is rife there too. I remember once going into a porn shop and picking up a Jap porn mag for a mate in Denmark. I flew out there and gave him the mag, which was still sealed up in the plastic wrapper. I thought it'd bee the normal 18+ gals dressed in school uniform. It was but it turns out in the back, it was full of child porn adds, complete with pictures - and I'd flown with it through an international airport. We were mortified.
So yeah - Japanese guys have some major sexual issues. Japanese girls in my experience are pretty cool - and I know a lot of them. I know loads of Japanese guys too and I know perhaps just 2 that are faithful to their wives of maybe 300 Japanese I've been with on business trips in Thailand/Philipines/Indonesia.
My personal theory on this is that Japanese dads are mostly absent and play very little part in raising their kids. The women end up fine but the men are all brought up by mommy.
Anyway - knowing the above, it makes it doubly worrying that any young Japanese man is carting infants off to Cambodia, where you child prostitution is rife.
