My erection/arousal fetish

I am not gay. However during the past 10 years or so I have become more interested in cocks. I especially enjoy being naked at nude beaches and watching other naked men playing with their cocks, becoming erect and eventually (sometimes) ejaculating. Just watching them become erect whilst I do the same is exciting. Sometimes I stroke other men's cocks as they stroke mine - but we do this out-of-sight, behind trees, rocks and bushes etc. I have always enjoyed mutual showers where "contagious erections" can take place. It is exciting to watch how one man with a semi-hard cock can cause other men to also become semi-erect or fully erect. I have masturbated on-line many times with other men and other viewers and on sites such as Chaturbate. My cock is hard as I write this. Many of my favorites on this site are communal shower videos where contagious erections occur.
