I (f28) female having sex with my on again off again (m30). When he smacks my face hard enough to sting but leave no mark. I personally feel the sting and try to let my body adjust and assess what just happened. Suddenly it’s apparently obvious that i became much more wet which pleases him. I want to understand even tho i don’t like being smacked during sex at all (kind of teared up when he asked if i was okay) why my body reacted that way.
