MDMA and projectile ejaculation

heh... Well it seems the past few times ive dosed pure MDMA ive had some pretty profound masturbation experiences. Usually Ive heard people have problems while on MDMA(or crappy street ecstasy equiv.) maintaining erection... however Ive found not only do I have longer and more enjoyable masturbation sessions but I tend to have incredible fountainous ejaculations that are very pleasing. I would like to share this sort of thing with a partner but everytime I roll I am too stupid to even consider flirting with someone else, let alone a sober or drunk girl(usually at parties). Has anyone else had this sort of experience with MDMA?
