That’s a interesting question … let me be honest with you.. it’s not(you are not a sex motor pounding her pussy like a printing press…)
but it’s necessary to keep your partner engaged , this can be like as simple as complementing her for who she is , foreplay(talk dirty ), gentle kisses on her cheeks, behind her ears , inner things… women’s body is a wonderful thing…it’s always fun to experiment …
If you are clueless it okey to ask your partner, what they like first..
A simple trick is to put her needs before yours.
I will assure you that , once you have got them all horney , wet and engaged.. they will do all in her powers to keep you entertained..
And lastly take good care of your self,
1) be well hydrated 3 to 4 liters of fluids a day
2)get adequate sleep 7 to 9 hours a day
3)restrict junk food and simple carbs
4) exercise (simple 30 min walking )at least 5 times a week
Such simple things are gonna do wonders for you when you are intimate with your partner..
Stay happy and happy fun..
