I had a recent date where I incorporated some tantric practices into a pse type date. Now the guy requested a pse but asked for "a taste of Domme* (Sorry, I don't serve Vegan Black Angus). We were able to work it out, but since it was so undefined to me (first date) I thought "What the hell."
Ended up doing what he described as "very relaxed but intense play" with non bdsm toys and orgasm control (I do that pretty much anyway, I think).
The tantric aspect came in with a focus on the feelings attitude, control the feelings, relaxation and breathing control, then ..ummm.."climaxed" with a countdown from 10 to blastoff. After nearly an hour of escalation/control, I was pleasantly surprised at how controlled he was during this countdown. Great audition and pretty damn hot too! We both definitely thought so.
So, who has used tantric control/focus practices in their play?
