The question is, why do you want her wet? For easier penetration? If so, my experience has been to start with oral sex, which I enjoy giving, then there`s almost always a point where u get from yr gfriend/woman, that silent (or maybe not silent) "ok, that`s enough of that, lets f*&k, put in inside me, lets make love." That sort of thing. Happy trails!
The best position for deeper penetration from my experience as a woman is to let her lay on her back legs wide open and you place both legs on your shoulders while keeping your hand beneath her buttocks and as you enter her you pull her towards you this is the deepest penetration position you can have.
Wow. After reading these and other online posts my heart goes out to men ! I never realized we, women, were both so complicated and that men knew so little. For deepest penetration have her lie on her back. Keeping her legs closed pushe them forward over her head then enter her. This will give you maximum depth. Next, vaginal lubricant is somewhat oily as created by the body. Water sex, pools, hot tubs, showers, etc. is NOT moisturizing and NOT comfortable unless you use an actual product in a tube that is NOT water soluble! Problem is it messes up our PH but once in awhile should be fine.
Fore play consisting of sucking nipples, fingering her, playing with her clitoris(go slow and mils as it is very sensitive. If harshly treated, it will go numb),suking vaginal orally will make her more wet.Rolling her breast clock wise and anticlockwise will excite her more.You may explore her body to find out sensitive points like ear lobes and any part of the body. Everyone has different sensitive parts. You have to experiment with different parts to find out sensitive points. You can stimulate her by innovative way. You have to become more creative to stimulate her. I hope this suggestion works for you.
The most concrete evidence that I've seen visually was a vibrator on the clit for as little as a few minutes or longer. May just depend on the woman. But wetness eventually becomes present.
Honestly, it all depends on the girl, and what she likes. If you somehow give her clitoral stimulation. That is often the best way to get a woman wet. Perhaps oral sex. Fingering her often won't produce the same sexual arrousal because the clitoris is what women really feel pleasure from. I hope this was at all helpful?
With you on your back, you could have her face you on top, and in this way she can control more of the action and what feels good to her. Probably the best position, however, is the "69" for oral stimulation, as mentioned above. Perhaps it would be beneficial to you to look up sexual matters in your local well-stocked library or go to a book store for a variety of sexual guides. It sounds like you are playing with fire.
Well oral sex is a good way to excite a woman more. Some women will not get extermly wet.
For your second question I am not sure what you are asking. What position is best for the deepest penitration? If so I suggest trying different positions and figure out for yourself, it's more fun that way.
