while entering initially is about safety. A lady wanting or needing to go slow at the beginning is
NOT evidence of her not really enjoying Greek. For example, I am someone who doesn't like FIA, so I am never "open" prior to Greece.
It is incredibly painful to have someone force themselves in when the sphincters have not sufficiently relaxed. I had a client do this once, after I'd said "go slow and wait until I tell you I'm ready for the head" He decided that going in quickly (like ripping off a band-aid) was a good strategy. I almost passed out from the pain. He had no idea how badly he'd hurt me by doing that
That said, once it's all the way in, more aggressive action in that area can be a good thing. I love Greek, even more than the front door. For me, it depends on the size of the guy's equipment. The larger it is the less intense pounding I can take. That's just me.
