I trust that you appreciate what you have. It is not so much the psychedelics, it is having a partner that you are so close to, that the majority of us are not privliged to have.
). I think that might be more to do with our ourlook on life in general though because even totally sober we both seem to be able to identify the comedic & absurd in day to day human behaviour (it's one of the things that really cemented our relationship early on). Given something like a psychedelic we both tend to see more absurdity & comedy in things around us, so turning that viewpoint inward if we were to start having sex is basically doomed fromn the word go because we both see the comic potential & neither of us can shut up and not comment on it (which inevitably results in both of us falling about in fits of laughter). It sometimes happens when we are both utterly sober, so if sex is that funny without drugs, what chance does it have if we're both being giggling idiots? 
sex on lsd is weird...very easy to get distracted and lose interest. my mind sometimes goes on bizarre tangents so one minute it's "girlfriend-love-sex-love", passioin enveloping us like swirling curtains of sensation... and then it's "universe-love-girlfriend-banana-guitar-sunrise-girlfriend-love-girlfriend-simon & garfunkel -" and then i find myself flacid.....
Making love was a true sensory delight. The sensations, the smells, and the sight of my love’s naked body with an aura of light around her were almost overwhelming. We made love with animal-like passion and ferocity. But we also felt intense feelings of love and empathy beyond just the simple lust. The words, “I love you”, must have left each-other’s lips a hundred times.
As the peak approached, I became seized in fits of absolute of hysteria and my laughter became uncontrollable. At one point, I started laughing once while Winding Vines was initiating another round of love-making. I was not laughing at her, but still ended up having to explain myself so as not to offend her. At times I was laughing so hard, it was difficult to catch my breath. Again, all of this reminding me very much of psilocybin mushrooms which produce much of the same effect.
