So, the girlfriend and I were having sex before and something new happened for me. Being relatively experienced as a guy with different women, it caught me by surprise, but I think we discovered what they call the "AFE" zone. (anterior fornix erogenous zone). I googled around for what happened and I'm 99.9% certain that is what we discovered...lol like columbus? (who was an asshole by the way) Anyway. The sensation occurs when I'm really deep inside of her, firmly but slowly pushing in (we both enjoy slow sex, none of the bangy-bangy rabbit stuff...most of the time) and there is a sort of soft, caressing "plop" sensation on the tip of me. We both were like WHOA and after a little movement I was able to replicate it. A slow pull out, then gently pushing until it happens again. She said it feels fantastic and hasn't felt it before with me (or her past lovers). The best I can describe it is like something falling into place...sorta like when you move a gear shifter in your car, you move it one direction until, plop, it finds it's niche. We think that the tip of me is squeezing between her cervix and the very end of the vagina wall. We are fairly sure this is the AFE, because it feels more or less pronounced, depending on the time of the month. (the cervix changes slightly in shape and protrusion depending on cycle,...right?) so yeah. We think what is happening is that the "plop" inside her is the edge of the tip of my equipment sliding past her cervix. Since I don't have one of those awesome mushroom heads, we fooled around and we put a cock ring on that does a great job of keeping me extremely engorged and the tip edge more pronounced (which we've done before for fun) and the snug fit inside her in the AFE was even more pronounced. So yeah. Great stuff. We both like it a lot and try it when the mood is there. I'm wondering if anybody else has experience or knowledge about this.

It's so nice to discover something new (to you) about sex. What I love most about intercourse, if we're talking the physical sensations alone, is the feeling of fullness. The very tight fit of the cock inside. When he's moving out, suction kind of pulls my vaginal walls, really as if being sucked from inside. It's a fantastic sensation. When my husband is deep inside me, sometimes I just stop all movement, and I can feel that strong, delicious presence, the after taste of friction. I feel my best when he's deep enough I'm being stretched, every little part of that internal canal is being stimulated. And the fact it's being stretched, it kind of pulls the tissue from my clit, indirectly massaging it by successive pulling and letting it go... repeat. It's awesome, too good to describe with words. Talking about the cervix, when I had one, it only caused pain. I enjoy sex a lot more now. It helps his cock is the most beautiful and perfect cock in the planet, as far as I'm concerned. Yes, I'm very biased.
