Seriously, I have very little experience with taking higher doses of cannabis because I do not use it as much (partly because it is expensive, partly because it results in sleeping without dreams and I like dreams, and partly due to my already low blood pressure - I do not want it to fall further) and when I do use, as a sleep medicine, I take tiny non-psychodelic quantities, but on three occasions when I took larger doses, it made me less inhibited, sexually, and I really liked that.

So why not try it to see if it can result in an erection? At least it is safe .
