He's way more experienced

This guy I'm talking to wanted to play truth or dare and I asked what his body count was and he said 52. He's the only guy I've been with sexually, is that dangerous? I saw a chart said the higher the count the higher you've possibly been exposed to STD/STI. I like him and I'm not judging him on that but I feel weird. But he's also a little older so I can see why the number is high. Btw I'm 18 and he just turned 23
