Guys, why did he do that?

So a colleague of mine randomly said to me, “you have something that I want” he’s not normally that direct so I was surprised. Then when I walked over to say good bye he pulled his chair back a bit so that I would definitely talk to him. Because he pulled back his chair his legs/ crotch was no longer under the table so he put both hands on his crotch, lifted them up and threw them back down & kept smiling. Because he did that I couldn’t help but look there a few times wondering what was that. We chatted for a bit.
I am still wondering what that was all about since he has never done that before.
