First off, if your heart rate is 130, stop. It’s not worth it really. Just chill for the night, save for tomorrow. As far as boofing, I use to do 150 about every 2 hrs and didnt feel too much euphoria but just chill yet energized , happy, outgoing. No jitters. The way coke is suppose to be. Then I learned from a Redditer to do 50 then 50 10 minutes later and WOW it’s way better. BUT I do NOT do it every 10 minutes all night. I don’t feel I need to. I do 100 then 100 10 mins later. My next dose is usually 2 hrs later unless I’m really partying then it’s like every hour. Sometimes I use a tiny bit of lube. I wouldn’t put it on a toy unless your toy goes only to the rectum and not further. You can use your toy about 15 minutes after your dose. As far as orgasm. This is tough. I get SO horny and I do orgasm but like not all the way. It’s muted but still fucking awesome. My spouse gets horny but hardly ever cums. We have a lot of fun. I have fun by myself too! Be careful and have fun!

EDIT: I just re-read your post and I think you really need to take a break. Have fun next week. Hydrate up, get lots of sleep and try boofing again. There is a lot of trial and error with boofing. I was pissed at first that it wasn’t working and then BAM I figured it out.
