Gas smell only on cold start? (self.mechanicadvice)

I drive a 2008 4runner with 85k miles. It's been receiving by the manual maintenance for its whole life.

Recently I have started noticing a gas smell when I start the car in the morning. It seems to dissipate after a few minutes. I also don't really notice it on subsequent starts on the same day if I take the car out multiple times. Or if I do, it's less pronounced.

There is no visible leak or gas on the driveway that I can see.

Any ideas? I'm planning to take it in but figured no harm in asking here to see if anyone knows what I might be dealing with first.

Thanks!

Just checked this morning and it is not detectable inside the car. And it is definitely stronger near the exhaust (and/or is coming from the exhaust).
