I think the more attracted you are the more sensually stimulated/overwhelmed you'll be and hence nutting quicker, but that's just physical. With a greater emotional connection I can see what you're talking about.No it's not
Things we enjoy, we don't want them to end. Sex is no different.
If you are very physically attracted to her, you will train yourself to last longer. The more connected you are to someone, the longer the pleasure will be.
