This might come off as a dumb thread, but it's fairly serious. It's not as if I'm experiencing a loss of libido or anything. I've consistently been with the same girl for close to 5 months. Sex drive and everything is still good to go, however, it feels as if over the past month I've experienced a loss of sensitivity. It takes a significant amount of focus and effort to obtain an orgasm, and most of the time I won't even be able to more than once a day. Obviously, it won't feel quite as good if you're having sex so frequently, but I'm wondering of any supplements or natural remedies I can take to improve penile sensitivity and make it easier to orgasm.
