Every time I try a new toy up my bum, my body starts shivering, knees shake and I feel like I am about to faint! Now it's not really a bad feeling but more like orgasmic without an actual orgasm. I just become very weak until it goes after a few mins. Not sure how to explain. Happens pretty much when I try something a little larger than the last time. I'm occasional user if that helps! Not freaked out but curious, what that might be?
Is the object connected to a wall outlet? You might check for a short circuit in the electrical system! Perhaps the sensation you felt was a circuit breaker overloading. LOL
that feeling is just what we're all after isn't it........? if it's each time you use a new toy maybe it's anticipation? how big is your current toy? Simon
