Exactly what the title says. I like intense sensations, and I love having the opportunity to induce intense pain without having to cause any permanent damage when it arises. I rubbed salt into a blister on the back of my ankle this evening, and it was great. I enjoy feeling the different waves of pain, how the sensation occupies your whole mind, then eventually fades into warmth and relaxation. It’s not a self-harm thing, I just enjoy it.
