Wish I didn't do it at all but I probably do it 2-3 times a week. Can go a month without it (but is difficult). I don't want people to tell me it's okay/healthy w.e, just a personal choice. I'd rather not do it at all tbh. But I'll be married soon so won't have to worry about it then haha.
In all seriousness tho - 1 guy said he did it cause he's boored. I'm probs the same. The busier I am in a week, the less likely I am to think of/do it.
