Hi there. Long-time reader, first-time writer here. Hoping for some advice, because one of the best things about this forum is shared experience. I have no trouble getting a nice hard-on with my partner: in fact, normally just holding hands is enough to get me going. I occasionally like to cam with others or play around in the gym-shower, but I can't get a full hard on in such scenarios. Anyone else experienced this? What's going on?
