I am a 36-year-old man. When I was a child, I was taught about sexuality by a few people, and I always thought what they taught me was correct. As I grew older, however, I came to understand that what I had been taught were homosexual acts. I then switched to being straight. I am addicted to porn and masturbate daily. After my marriage, I have been fantasising about threesomes, and I also like to see my wife with other men. We have had five or six such experiences. Is this normal? Why do I like to see my wife engage in sexual acts with other men ? We have a good relationship despite my fetishes. I find that I have a very strong sex drive.We have sex thrice a day, and I even masturbate. I think about sex most of the time, which makes me less productive at work too. How I can control my desires and fantasies?
