Is it normal to like physical pain?
Yes, some people enjoy controlled physical pain, whether as a sensation, part of intimacy, or for other reasons. It’s mainly a concern if you feel driven to injure yourself, can’t control it, or the pain is unwanted or causing harm.
You’re not alone: people can enjoy certain kinds of pain or intense sensation, especially when it’s chosen, predictable, and under their control. For some it’s part of intimacy; for others it’s simply a sensation they like. It doesn’t automatically mean anything is wrong with you.
The important line is safety and consent. If another person is involved, agree on limits and make sure everyone can stop at any time. If you’re causing yourself injuries, the urge feels hard to control, or pain is becoming a way to cope with distress, talking with someone you trust or a professional could help.
