Watching My Son.

I'm Ramona, I'm a 36 year old single mother with a 15 year old son . For some reason, I just can't stop looking at my son's body. He walks around in his boxers and no shirt. Nothing unusual about that, but now I see his half hard cock swinging around in his shorts. Two nights ago, after his shower, I walked by his room and the door was slightly ajar. He was standing in front of the mirror, nude, doing muscle poses. He's trim and muscular and surprisingly big. I was so wet that I went to bed and rubbed out a shaking orgasm . I'm wrestling with this entire thing, I know it's wrong, but he makes me nervous and edgy.

Can any women relate to me issue ?
