I haven't tried anything sexual on Salvia, but Hippy-Flipping (MDMA and Shrooms) was actually amazing. The X we took wasn't tweaky so the amphetamine was low, thus not making the erection impossible. The joy of hippy flipping is that you have the mood elevator while the psychedelic is taking you to another dimension. In all actuality, we went at it for about 4 1/2 hours. In our minds there was no time, there was no measurement of anything actually. That night we lived lifetime together, We met, fell in love, grew old and died together, then that next morning we realized we had another lifetime ahead of us.
HARDCORE bonding though, beware who you hippie flip with.
On shrooms alone, having fun is just that! Depends on how hallucinogenic the shrooms are, is how crazy it is. If you are not in reality it is a tad overwhelming. If its a mellow, or medium hang our, fun trip kinda thing, go for it. I love it!
