I've recently been approached by a sub who is about 20yrs my junior. I am a woman, and I have a lot of personal feelings about gaps like this, as I dealt with predation in my adolescence. Not that I'm predatory, just that the power imbalance is a lot. They are very attractive, and willing. New to kink, new to a lot of things besides masturbation and quick flings. I'm married and not looking for penetrative sex- yes, my husband is aware of all of this as well, he's super monogamous, and I'm just not. The sub knows this, and wants chastity and service work, but I worry about him and the many issues that can arise from the situation. He has his own place, went to trade school. He's not an idiot. It's flattering he's interested. I told him about my apprehension, and he insists he's happy to try and see if we can make anything work. This makes it feel a bit like he's just desperate for a female dom. Am I crazy for saying no? If I didn't care, I would just say yes to play with him because he's so pretty, but I'm not really casual about anything I do.
