Marijuana Effects on Orgasm?

Hi Dr. Mia,
I find my best orgasms occur during sex when I am high on weed. Is there a physiological reason for this? I have often thought that it just simply might be that I am more relaxed in my head. Hope that makes sense. I seem to have something akin to explosions in this state and the orgasm seems endless. Almost to the point that if I dont stop I feel that the pleasure will kill me! Does anyone else experience this?
