What I also suggest during sex is [this simple penetration technique that can yield tremendous staying power for you,](https://www.reddit.com/r/askingpeople/comments/1q9smb4/ultimate_sexual_stamina_program_the_blueprint_to/) and yet put her on a continuous sexual high at the same time.
This is what you do…
Perform eight shallow thrusts about two to three inches deep, and then one deep thrust. Follow this up with seven shallow thrusts and then two deep ones; six shallow thrusts followed by three deep ones.
You get the idea.
Continue doing this until you are performing nine deep thrusting movements. Then repeat the entire sequence again.
Why does this work so well?
First, deep thrusts are the ones that bring your penis closest to orgasm, as the frenulum (the stringy thing in the "inverted v" under the glans) and shaft skin are stretched the most, causing greater arousal. [Varying shallow and deep thrusts](https://www.reddit.com/r/askingpeople/comments/1q9sp2p/thrusting_into_her_pussy_switching_penis_angle_of/?) will help taper off the stimulation on the penis glans/head. Second, the first three inches of [a woman's vagina contain the most pleasure-seeking nerves](https://www.reddit.com/r/askingpeople/comments/1q9snxx/female_ejaculation_unleash_the_ultimate_gspot/?) and the shallow thrusts will stimulate her really well.
