It’s a good question. And occasionally becomes a real problem if being so horny keeps you awake too long. We all need sleep, even on Stuffed Saturdays.
Firstly, if you’re just a few days in, don’t worry, it’s normal and you will just get used to being hornier and falling asleep anyway.
If it’s really interrupting your sleep though, you can try cutting out the last edge of the day, or try a shower and non erotic read AFTER that last edge to give yourself some time to calm down.
Beyond that, the usual advice, get exercise during the day, avoid caffeine, cut out screens in bed.
An alternate approach is find some bimbo hypnosis recordings and listen to those as you go to sleep. They’ll distract you from your own cravings and take you somewhere far… deeper.
