I have a question re: kegel exerciser toys (I was looking at the CalEx L'amour.) Are they necessarily for women who are a little "loose" down there, or could they also be helpful for those who are already tight, but want to enhance their orgasmic experience? I was under the impression of the former, but I'm curious about them, and if they can make my orgasms even BETTER, I definitely want to try. Also was wondering if they can make you uncomfortably tight? I can barely take my husband as it is and I really don't want to be that much tighter. Thanks!
