Go to a munch. Meet some people. Share stories, knowledge, techniques. Perhaps go to a party when you're both comfortable, to at least watch.

Then you can experiment.

I can see his issues with his mother (or yours for that matter) in the house. There's no way to hide the sound of a slap or spanking or flogging, or the moans that go with good session. Do either of you want to explain that to "mom"? Or take the consequences if she becomes outraged? I'd "bet" your activities are all quiet ones. So go out to play.
