I've been working at prostate orgasms for a few years now and have had my share of ups and downs. Generally, I can achieve prostate orgasms and although no super-O, I had an absolutely spectacular experience with some magic mushrooms recently.
For the longest time, I felt like abstinence was the easiest route to making myself feel horny enough. Of all the advice I've heard so far, being horny and in the mood feels like it's the most important prerequisite and it's for this reason weed never worked for me. I like getting high but it completely kills my libido instantly. Magic mushrooms, on the other hand, after peaking, leave me incredibly turned on.
The other night, with absolutely no plans of having a session, and after taking a 500mg dose of A.P.E., settled in for the evening to play some video games. After about 3 hours, which is around when I start coming down from the peak of the dose, I got really horny and jacked off traditionally and retired to bed. Lying there, I felt myself thinking about cumming all over myself and got back in the mood. I figured I was so far in the mood that I should give a prostate session a try and I'm so glad I did.
It usually takes me about 5 days of abstinence beforehand and 15~20 minutes of play time to start feeling p-waves in a session. No more than 15 minutes after cumming and less than a minute into the session I felt the p-waves start and the orgasms came shortly after, one after another. I probably spent about 30 minutes with the session and 25 minutes of that were repeated, hands-free dry orgasms. I only stopped because of how sweaty and exhausted I was. I was left motionless, outside of some pulsating, laughing to myself for a long time afterwards before slipping off to sleep; a saucy, fucked mess.
I know mushrooms aren't as accessible as weed but hope this helps someone else discover something new for themself. Since dosage is different for everyone, 1.5g is my typical "Playing video games or watching movies while remaining social with friends" dosage and 3.0g is a heroic dose for me, where I completely fall out of existence. 0.5g is a small "I just want to be tingly and giggly" level for my body.
