Basically, whenever i try to WILD, after about 7 minutes, i start to get a feeling on a part of my body, like a sting. Since not moving is required to achieve WILD, i try to resist itching. It's easily resistible at first, but it starts getting worse and slightly painful. I also keep feeling like i have to swallow. These two are the reasons i usually give up and just sleep normally. I've had two WILDs so far, and the stinging/swallowing thing didn't happen then.
Is this my brain testing whether i'm asleep? If so, is there any way to avoid it?
