All good comments ahead of mine. Not stated enough, your feelings towards certain acts ARE NORMAL and even though they match the JW practices doesn't mean you aquired them from the JWs. I have been married three times to women who were never associated with the JWs and there feelings are the same. You must have said "I am not in the mood tonight" more than once in your marriage, and if you have power to say that, then you have the power to tell your husband what you define as the difference between sex and love making. Acceptable and not acceptable. A good marriage is based on many thing's, respect and communication are two good ones. I had always inspired conversations on sexual issues because I never wanted a woman to feel compelled to do something that may make her feel degraded.
As for the JWs that you see. I have never allowed a JW to shun me. I approach them and start a conversation. They will talk to you and do you know why? They are always looking for a door to open so they can preach. I keep the conversation to 10 minutes or less, never giving them the opportunity. It feels very very good.
