I (28,F) like a guy (31, M) – is sleeping with him on the second date too soon?

I'm a 28 year old woman living in Europe. I met a seemingly great guy (31, M) and am wondering if sleeping with him on the second date makes my chances of properly dating him less? Here it seems like people often sleep together on the first or second and I would like to. So from that perspective, I think I will. But I'm just curious if other people think it makes me someone he'll want to pursue less?

​

TL;DR – when is it too soon to sleep with someone?
