I'm sure you get posts like this frequently, but I'd like to explain what specifically is leading me down this path to see if anyone has any specific recommendations for me.

Me and my wife have been together for over ten years now. At first our sex drives were pretty well matched but as time has passed her sex drive has increased while mine has either stagnated or decreased, depending on the day. We've made up for this by branching out over the last couple of years by inviting other people into our bedroom, and it has been great but lately I've been looking for ways to improve sex just between the two of us.

On a more personal note, several years ago I began practicing mindfulness meditation for the purely practical purposes of helping me improve my ADHD symptoms and was pleasantly surprised by the unintended side effect of it greatly improving my spiritual life (I'm Christian but am comfortable enough in my faith that I have no trouble reconciling other spiritual practices with it).

I'm highly interested in applying a kind of meditative approach to sex that could serve the dual purpose of helping me please my wife while also enhancing my spiritual life. This in spite of the fact that I have to confess that in the past I've had kind of a stigma towards tantric sex and the sort of stereotypical male you might imagine who practices it.

SO: Where's a good place to start if I'm looking for a practical guide to beginning this practice?
