I’m literally suprised, no, shocked, that no one has given a response to this. But I’ll dive in first…
In my mind, it’s the look in your lover’s eyes that makes me stimulated more so. The physical part is just an after-effect, but the way both parties look into each other’s eyes, locked in to each other’s pleasure & stimulation, working together to reach a satisfying conclusion, no matter how long it takes…sorry, dipped out for a second…
I’m more a sound guy, but I found this is what I experienced in my recent encounters. Hope this answers, in some abstract way, your question & maybe get more responses.
