Current Blog: WE LIVE TOGETHER mentioned it was common for a man to get an erection, the first few times he visited the park, but it goes away after you're there for a short time. You get use to being around nude people, he explained. Even so, he added, every so often you get a hard-on, usually when new people join; but you just put a towel in front of you until it goes away. I told him I'd be too embarrassed, until I got "use to it."
