It's not a matter of legal that anyone is questioning. You're talking about a guy who needs to uphold an image for his job. People have posters, books, mags, memorabilia with this guy all over the place and now every time they look at it they are going to think of him beating off. It does tarnish the image of the band and as a result, they may very well cut him loose. A teacher has every right to jerk off on camera to a 19 year old too but if it was your math teacher, he'd be collecting unemployment and you know it.
