For me - 1 and 2. While I've watched her and sometimes like to participate - I like when she sneaks around behind my back to have sex. Usually she'll tell me about it later - "Honey - I went to so and so's house and we had sex this afternoon". Sometime I don't know until I have her in bed at night and notice her pussy is wetter then normal. I love when I'm in her and she'll tell me about some tryst she had earlier.
