Whenever I smile, it seems really needy/creepy, even though I mean it genuinely (e.g. meeting a friend, personal achievement, photos, etc). I also smile a lot, because I used to be unapproachable with resting bitch face. Smiling for prolonged periods also seems a bit creepy, even though, again, it's completely natural.

Perhaps it's in my head (pun intended). Basically my smile looks like this. or this..

The last thing I want to do is to give off a needy/creepy vibe when I'm flirting and kino escalating...
