Try some deep breathing. Taking yoga classes inadvertently does wonders for your sex life just from learning how to breathe correctly.
You may not even realize you’re doing it, but many women react instinctively to encroaching orgasm by holding their breath. *RUDEBUZZERSOUND* That’s not going to help you! Try to be more aware of how you’re breathing. The goal is to feel the sexual arousal your body is experiencing and then EXPAND it by taking a deeper breath which draws out the pleasure even more.
Breathe deeply into your pelvic area. I know that sounds weird, but when you slowly draw in the breath, visualize where you want it to go. Imagine that you’re sending the breath into the vaginal canal before slowly exhaling through the nose. This creates oxygen, decreases tension, and increases blood flow in the pelvic area. It has a HUGE impact on your sexual pleasure. Trust me.
