Yesterday was, I would hazard to think, the most sexually and romantically thrilling day I have ever had in my 28 years and the best acid trip I have ever had in my life. I think it was just as good for her, too.
You should try it with your lover. The Salvia and GHB and nitrous are surplus to requirements, the important part is the acid and the fingerpaints. I got the shit they sell for toddlers so I imagine it is pretty non-toxic.
