Pretty much every person will experience a moment in their life where either their peen or their partner's didn't cooperate how they both would have liked. It's normal and it's totally fine. But if you're looking for a few ways to extend the length of your love-making, look no further than these five fixes.
If you're dealing with a partner of the premature variety, this position is a pretty solid place to start. Before (or regardless of!) you switching to a penetrative sex posish, have your partner go down on you, alternating light finger strokes on your clit. Starting with oral takes the pressure off of both of you: You're more likely to finish, and so he's less likely to stress about "letting you down" if he orgasms immediately later on.
With your partner kneeling back on his legs, he won't be penetrating you *quite* as deeply. This way, the sensation isn't as intense as other rear-entry positions. With your legs wrapped around his back, you can control the speed and rhythm to better prolong your love-making.
