Cheryl, this is my last post on this thread.
You would know better about your son. Just keep a watchful eyes, because it is not only about sex that he will be exposed to; there are other things - drugs, burglary, scams, etc... The examples I posted here was just showing you that because of what I did, I gain my son's trust that even during the time that he was confronted with an issue about sex during his adult life, he run to me for help because he knows I am always with him no matter what. I almost lost him when he was 4 years old. He was drown in a swimming pool. It was timely that I saw him. From that time on he would not go back to the pool to swim. What I did, I took him back to the pool, let him float again, did it again and again until he got back the confidence. One time when he was 14, boys 17 and 18 took him to a store to shoplift. When the guard saw them, the big guy left him to the guard. The guard gave me a call in the middle of my catering activities. I went to the store and told the guard who he was with. It was good that the store has a policy of contacting the parents first before the authorities if the child is below 14 years old; my son said to him he was 12 (he was tiny and cute then) From then one he was afraid to go back to the store. I took him back to the store holding his sweaty hand and I assured him nothing would happen there. I did it again and again until he got back his confidence. I admire your concern and I would say you are a very good mother. Be a friend to him first. Gain his trust and confidence. What I told him when he got his first job? I told him to buy a house, he will be the model to his friends and girls will be going after him. He married a a conservative, demure, accountant. She not one of the girls who chased him.
