Why do my guy friends constantly bring up my dating life?

I’m noticing a pattern where my guy friends will brings up my dating life quite a bit. I talk about other guys in my life and they say things such as “Maybe you should date him.” Or I say I have plans on the weekend and they ask “Are you going on a date?” Is this just friendliness or something more? I feel they’ve been subtly flirty before but I can’t tell whether or not this is just normal guy behavior.
