How do you tell a normal guy from someone who just wants to get laid?

I would judge by how they talk to you, namely whether they give short, non-detailed answers. The reason for this is that guys who message lots of women without really having a specific interest in the women will try to have more general conversations so that neither side deviates too far from the script. If they don't do this, they'll need to start remembering specific details about each girl and that becomes a nightmare to keep straight.

Disclaimer I haven't been peer reviewed yet on these findings but if they have any pictures with their shirt off or if they dress too nice they're usually a fuckboy.
