Re: We are the Night's Watch. Welcome to 'Castle Black' [GROUP] It's a finger applying pressure on the perinium. It's an old yogic technique. Usually painless, I'll add. My personal experience is that an orgasm without the ejaculation is less pleasurable, therefore less dopamine spike. I think also I wanted so bad -not- to ruin my streak, it was an extension of wanting to hold it in. I had two beers last night. Funnily enough, I only ever get this stinging sensation after ejaculation when I have been drinking alcohol. It's not an uncommon thing, a look on google will confirm.
