What does this mean??

So me and a group of friends were playing truth or dare but like a sexual version lmao. Well anyways, a guy asked me how many sexual partners I’ve had and I said 1. He started laughing so hard and then told me to tell him the truth and I told him I did and he said “well you don’t seem like the type to have only been with one person but ok” and everyone laughed. What tf is that supposed to mean? I actually feel like I don’t wanna talk to them again lol
