My wife and I have been enjoying anal sex for many years, but as a "special treat" rather than a regular thing. This started changing about a year ago, when my wife got her first bout of bacterial vaginosis. For those who aren't familiar, this is a condition caused by an upset in the pH of the vagina, causing the usual mix of healthy bacteria to get upset. When the bad bacteria take over, it becomes itchy and smelly -- not a threatening medical condition, but a big downer.
She went through several cycles of vaginally-delivered antibiotics, which have some downsides themselves, but cured the problem temporarily. The BV would always come back after a few weeks. The issue is how to control vaginal pH so that the bad bacteria don't get an edge. Semen is one of the factors that has an impact on vaginal pH, and based on some papers we decided to experiment going condom-only. After several months she has been BV free! So we have decided to make condoms a permanent part of our vaginal sex (we're done having kids). Since I tend to leak a lot of precum, I don't enter her vagina bare at all any more.
Because of all this, our frequency of anal sex has gone way up. Like most men I prefer sex without a condom, and for us that means anal sex. My wife enjoys anal but still gets off better from vaginal sex. So our sex tends to be: I fuck her vaginally with a condom until she gets off (she uses a vibrator also). Then I remove the condom and fuck her ass until I come inside. Anal sex feels great, and it's nice to get a lot more of it now.
I'm encouraging my wife to use the vibe during anal, to see if she can learn to come that way too. Ideally we'd get to a point where we'd have the option of going anal-only and doing away with condoms entirely. That G-spot is a powerful thing for my wife though.
