When You Realised You Were A Cuck/Slut Wife?

When do you first realise you were a cuck or slut wife? Was it a particular event that made you realise? Please share your experiences. I have described how I came t realise below.

I was only 17 at the time (I am now 29) and I had just started having sex with my girlfriend. I was her first, and being responsible we went to the Dr's to get her on the Pill. He wanted to give her a full exam before prescribing. She declined the exam and got the pill anyway. When she went back on her own another time he persuaded her to have an exam. She told me afterwards how she had to strip and he gave her a very thorough breast and internal exam. My gf was absolutely gorgeous upper class girl and I was very jealous that the Dr had gotten to give her such a good feeling up (which I am sure he enjoyed very much).

Then my jealousy gradually changed to a feeling of intense sexual arousal at the thought of another man getting off on feeling up my gf. She had a number of exams while we were together and she would always come back from the Drs and tell me how she had stripped and spread her legs on the exam table for the Dr to get a good look. I would go down on her and be licking her soaking pussy while she told me how she fancied the handsome Dr and she wished he would fuck her on the exam table.

I am no longer with her and would love to find a woman who would cuck me.

Hope that is of interest to people. Lets hear yours.
