I am a 57-year old, attached, athletic, muscular, 5'9" professional man looking for a discreet outside affair, a sexual relationship that may be casual and short-term or, if it clicks, may become long-term and even monogamous. I live in SF and I'm looking for someone no more than 50 minutes' drive away. If this works for you, please send me a photo and tell me about you, we'll go from there.
