I call them "masturbation races." Love them. As another reply said, society makes guys uptight about cumming too soon. So in my 20s I always went out of my way to slow down and hold myself off until the other person started to cum, then I'd let myself go. But by 29, I stopped giving a fuck and liked being first. Especially because, with women, it usually meant I could cum twice in the time it took someone else to cum once. Now I can't do that. I wouldn't necessarily say I take a long time to cum. More that I need something beyond just the mere mutual masturbation to set me off. A particular dirty thing the other person says. A particular view of their genitals. And a lot of the time, the other person cumming will set me off too.
Not that it’s a race but I do tend to cum pretty fast unless I can focus and slow my breathing. Second round I last much longer
