Lustful grandmother wants to have sex

I live with a very sweet man, and he gives me complete freedom in what I do. There's a reason for that: my boyfriend has difficulty walking, so he doesn't like going out. Our relationship is otherwise good, but I miss going out, dancing, going to the movies, or just having a nice meal. I could use an extra friend for these occasions.

I notice that my boyfriend feels physically older than me, and that's where the bigger differences are unfortunately coming in. While I still want to actively enjoy life, he prefers to do it from the couch.

It seems a bit vulgar to say what I really want, but the bottom line is that I'm not satisfied with my partner. He tries, but not to my full satisfaction. And if I'm being selfish, so be it. But I don't want to continue like this, so I'm looking for a man who can make me happy.

Age doesn't mean anything. In fact, the older I get, the hornier I get. Experienced men who know how to treat a woman are welcome. But also inexperienced men who would like to learn a thing or two.
