Being the only man to have responded this may seem shallow but do you share a lot of intimate foreplay before engaging in sexual activities? For me, back when I was with a fun and sexual partner, that would really do the trick for both of us, the intimate almost teasing touches and passionate kissing, even a bit of sensual massage. Having been a surfer all my life the only way I can describe it is kind of like a wave, it starts slow and small, then begins to swell and rolls you both into something all consuming and beautiful. I think love, trust and an ability to block out the rest of the world for those special moments really ties it all together.
