Light BDSM Question

During sex with my fwb I noticed I get really aroused by like, light pain I guess. For example when i get bruises I touch them and it make me horny or having my nipples pinched or being spanked. How do I try to incorporate more intense actions into my sex life? I tried hair pulling, don’t really care for it. being choked, loved it. I’m thinking maybe some bondage, light whipping, or something else ? Any beginners suggestions
