Sign that I'm bad in bed?

Every guy that I've slept with has came during sex within 2 minutes. It's not a problem for me and I kind of took it as a compliment, but they can't really get hard again after cumming with me. I've heard other girls say that they can go 2 or 3 rounds with their boyfriend and that the boyfriend will cum during every round. All the guys I've been with have came really fast and if we do a second round, they will go soft or they won't cum. Does this mean the guys I'm with aren't enjoying me or something?
