Once in a great while, when the dating gods have been cruel, I fuck myself. This started about 5 years ago after I had a 6 hour marathon wanking session, brought on by some high quality MDA pills. Wanting to repeat the experience, but without the drawbacks of mdma, I did some research and ended up with this.
I break out a little box with several bags of powder inside, a cannabis pipe, and several vials of liquid. The cocktail includes 5-meo-mipt, 5-meo-dalt, high grade cannabis/hash, and poppers. To prepare, I eat 1000mg niacin, and 1000mg l-arginine. Next, I will make a capsule of 5-meo-mipt containing about 5mg and ingest. I follow this with several dabs of high grade cannabis hash.
I begin by browsing porn to que download on the way up. I browse several sites and start the downloads, meanwhile downloads from previous sessions have completed. This method constantly leaves me with fresh, new porn, but with the thrill of waiting for what you want - which builds the energy. After about 20 minutes or so, my pill has kicked in. The 5-meo-mipt has an mdma like feel to it, and has a very sexual feel to it, making every touch absolutely amazing. Unlike mdma though, it has no push, doesn't interrupt erectile function, has neither no tolerance build up, nor debilitating hang over.
I'll hang out in this "zone" for as long as I feel like it, as we've just begun. When I find a scene I like, I will increase the sensation by vaping a little 5-meo-dalt on top of some cannabis. If I'm really revv'd up, just taking one hit might be enough to push me over the edge on the spot - without even touching myself

Sometimes I cum a little, without orgasming. This is especially devilish as it extends the plateau. This substance has a brief but intense physical push and temporarily increases sexual feelings when smoked.
If things still haven't gotten to the depraved-frenzied-overworkedpervert level that I crave, here is where I hit the poppers. One deep inhale, and I become obsessed! I simply can't leave my hands off of myself at this point. Most times, this is where I lose my load, but i might hang out and repeat this several times, depending on how much Im liking the scene. I'll sometimes stop completely, take a dab of hash, which starts everything all over again. If I blow, I'll hop into the shower, which feels incredible. The sensations from the shower, along with closed eye visuals of the women I just watched, rejuvenates me, and I'm ready for a second, third, or even 4th time around. The 5-meo-mipt will give you sexual vibes for about 4.5 hours before it changes gears into chill mode, though you can smoke it to decrease the timeline of events to about an hour.
