Did my first injection Friday night. Started with 5u on the right side and within a minute was fully erect. Remained hard after orgasm. This lasted about 3.5 hours, at which point I chewed a couple of Sudafed, did some squats, and took a cold shower to finally get it to go back down. Tried 3U last night on the left side and got absolutely nothing. I don't feel like I missed, but not really sure what else could have happened. I can't see 2u being the difference in working a little too well and not working at all. Plan on injecting for the third time tonight, but not sure if I should try 3u again, or go back up to 5. Trying to get things dialed in so I'll have a good idea of what to expect before I test out PIV.
