I'm late to this discussion but wanted to chime in as another gay guy who cams.
I'm with
@Vixxen81, I don't tell hardly anyone, especially family. In my case I have a couple of other employment channels so those provide cover. The person who knows the most about my cam work is my spouse, who I think doesn't quite get it but knows I enjoy it so he tolerates it and maybe appreciates aspects of it. As you mention, this job provides an outlet to people who might otherwise be feeling alone, and he gets that part. I also have a couple of friends who know I cam, but not family members.
So question would be, do you need to tell your family at all? In my case I don't think my parents would be too fazed, but at the same time I'm not sure what the point of telling them would be.
But I also wanted to talk about the shame you mention. I'm glad you're not ashamed of it I love what you do. Yes, there is a taboo to this work, but that's because people have hangups over anything sexual. And yet we're all sexual animals, with sexual needs, and camming allows us to provide an outlet for people to fulfill those needs. Then as you mention, you are providing a social outlet to people who might otherwise be isolated. Who knows, you might be the only gay person they know, or who they can interact with and talk freely with. A lot of the interaction I have with guys in my shows is not explicitly sexual - we talk about travel, the weather, hobbies, TV shows, all kinds of things. But then we can also talk about sexual things, without judgement.
It's been a month since your post, I'm curious what you might have decided!
