Yeah, I'm not saying there's something I don't understand.
It's just I'm the type of guy who's unwilling to even take aspirin for a headache, so the thought of pumping my body full of chemicals just to get an erection perplexes me a little. I simply don't put drugs into my body, and am a firm believer in letting my immunte system work as its intended. Minus vaccines, of course.
On the flip side, I drink alcohol like a fish, so go figure...
