I'm a 25 year old guy and have been having sex with a 35 year old woman. The sex has been great for the both of us. The problem is that she has a 13 year old son and he is obviously not stupid and knows what is going on. He has seen us the morning after when the both of us get up. Sometimes I get this s**t eating grin from him and at times does make me feel uncomfortable. How would you handle this? He probably is jerking off in his room when I'm having sex with his mother. Don't tell me that we should go somewhere else to have sex - that strikes me of being dishonest.
