I don't really understand what you mean but if make a guess, do you mean how to prolong your sexual session?
If it's so, i may have one matter that may helps but do not know if they really works, have been a long time my army not working. POOR ME!
Anyway, i heard this from my friend, just share with you if this really work, Feedback to me when tried.
During session, try not to go for FJ, try getting foreplay, kissing, licking and stuff like that, when wanting to attack the base, try to breath deeply and blow out a bit slowly, and repeatedly breath deeply and blow out a bit slowly during the attacking.
Some may ask how deep to breath in and how slow to blow out, what i can say it's that, it's your own body, you will feel it.
That's what i learn from my friend.
So hope it helps you~!
