Is it normal to enjoy freezing?

I enjoy the sensation of freezing. I often go outside in the sub-zero winter temperatures with only underpants on and stay out until my skin starts turning blue and I start shivering uncontrollably. I love the feeling and I've felt happiest when extremely cold or suffering from mild hypothermia. In winter, I go outside in the freezing cold weather, then come back inside and have a warm shower, then go back outside and repeat this process, sometimes around 10 times a night. I get this weird feeling that I really enjoy when I continually feel freezing cold then warm over and over again.

About 9 months ago, I was staying with a friend in Canada during winter. It was -15C outside with powerful winds. When my friend went shopping, I stripped naked and walking outside into the freezing cold. I enjoyed it so much that I stayed out there until I went completely numb and passed out. When I woke up I could barely move at all and I felt really faint. My friend got home and had to carry me inside, where he called an ambulance. I then lost consciousness again and regained consciousness in hospital 2 days later. The doctors told me I was treated for very severe hypothermia and that I was lucky to not have any brain damage and still be alive. When I eventually got out of hospital I tried to do it again, but was stopped by my friend, who told me to see a therapist.

It's not winter anymore but I still have the really strong urge to do it again and get hypothermia, I still love the feeling of freezing and cannot wait until winter so I can continue doing this.

Does anyone else get enjoyment out of this?
