First Rule:
BE EXTREMELY CAREFUL. Try to find it by gently massaging her inside at different angles. You need to either be inside fairly deep or have her pretty contorted to reach it and this makes for easy accidental cervix hits. While some might enjoy this, my current one says she feels like she's being ripped in half if I hit it and we have to stop for a minute.

Are you familiar with the female anatomy inside? If not, do a search and you'll see that when aroused, the inside of her vagina bulbs outwards in the back. This means aim upwards in doggy, or downwards with her on her back.

Try to forget about your own pleasure and focus on using your penis to caress and massager her like it was a stiff finger. You have to work on hip position and angles. Gauge her reaction by watching and feeling for any involuntary twitches or spasms. You'll only know exactly where her hot spots are if you go fairly slowly at first, working your way around inside with longer to smaller strokes in a closing in pattern. Focus on different areas inside her and study her reactions. She must be highly aroused, as the increased bloodflow makes her hot spots more sensitive than during a casual quickie to get you off.

I've had much success starting from a basic missionary with myself upright focusing on her gspot, then leaning forward to kiss her neck while moving knees back together and almost straightening my legs. I then scoot my hips forward, maintaining my body on top of hers, heads next to each other, and use my hip flexors to thrust downwards. I start with longer strokes, shortening the distance I pull out every 7-13ish strokes until I'm only moving about 1-2 inches back and forth right on the spot that gets the most reaction out of her. I stay there for however long it takes for her to explode, while running my hands over her and through her hair while kissing her neck/ears/face.

If you're going to do those extra things, be certain to keep a rythm so you don't distract her.

Good luck.

That seems strange that your girl would feel like she is being ripped in half from carressing her fornix...I think you may be doing something wrong fun...

Basically the posterior fornix is the deepest part of the vagina...You would have to aim beneath the cervix when trying to reach it...Because you go too high you risk penetrating the vaginal wall you aim in the middle you'll hit the cervix. Just go to the SI home page and look at the diagram. Look at the area below the cervix.

I meant that she feels like she's being ripped in half if one of us slips up and hits her cervix.

Oh...ok haha I was gonna say...that seems strange haha

Nice to see the guys working it out! Funin - you're doing this well. Excellent positioning and excellent explanation - congrats!

Just as you vary in size, so does she. You will have to 'experiment' and 'explore' a bit to find it - just watch her reaction.

I'd say her reaction is the only bit that matters. What's the point if you medically are hitting it but she doesn't care? That is unless it's one of those things where it needs proper stimulation for a period of time for the nerves to start making the necessary connection. Sometimes my girl just wants me all the way for the sake of closeness, regardless of the angle and physical stimulation.

Internally, I can sometimes feel more texture to her over that spot, and massaging it causes her to walls to spasm around me(side bonus that what's great for her makes it great for me). She also gets quite a bit wetter after a minute or so and occasionally squirts. The squirting thing is pretty new, but then again so is her consistently having orgasms.

Externally, it's always a different facial/body reaction, but you just know.
