Punting has definitely made me better in bed; a much bigger deal then the madz bedroom skillz it has given me (irony intended) is just the exposure to the sheer number and variety of female bodies. That means it doesn't faze me to see a woman naked (I still love it, but I don't get all flustered anymore which is nice; being scared of sex is shit when you have a bloke's relentless hormones) and I also care less about their looks.
When I was a teenager I was dumb and thought that someone had to be with a filthy young hottie to truly enjoy sex. Imagine my surprise when I found that (a) most women look good to my cock when they get naked, and (b) hot women can be terrible in bed compared with ugly or old women. Having shagged a lot of good looking women and even more not so good looking ones, I now feel that the looks side is nice, but just a bonus (within limits obviously; I'm not suggesting a toothless 50something crackhead on the street is going to give you a good time).
But, for example, just recently I was looking for a girl who did anal, and came across a good-looking Polish lass. Sadly, she was a bit of a clock watcher and had a bullshit rule about only allowing anal sex for five minutes (despite specifically advertising as someone who did it in her profile). I ended up leaving a bit disappointed and will not be going back (she wasn't terrible, but it wasn't memorable sex either). Then recently I had a good time with a chubby Brit girl who loves anal (well, for $$$ she does...). Of the two, the Brit is much less 'hot', but she'll be getting my business again in the future, because she's more trustworthy and delivers a better service.
