Round 2?

So my man and I have sex and it doesn't last a long time. We do foreplay and stuff like that before hand to get both of us going. Then we have sex, he cums and that's it. No round two. I hear and see people constantly talking about how there is a round 2 and that their man can get hard again. My man needs to restart like a 1980s computer. So if I'm lucky I will maybe get it once a day and that's it. Also it's not as though he doesn't pleasure me because there are certain times where he does and I'm able to cum. Trying not to compare myself but girls are talking about cumming 3 times after 2-3 rounds of sex. I'm not sure if there is a solution to this but I just kinda felt like ranting and complaining to some girls that might understand...
