What are the pros/cons of dating a busty cougar when you are 18?

I kind of view it as gross, in the same way its creepy for guys to be involved with young women.

Assuming that she's not a psycho bitch who's actually going to ruin your life there's not a thing wrong with it. Go for it. You'll learn a shit tonne of great stuff about sexuality and interpersonal relations and it will really put you ahead when you start dating girls your own age.

I lost my cherry to my sister's best friend, who was about 10 years older than I. Big, firm tits and fucked like a monkey in heat. The kicker was that she was in a relationship with the guy she eventually married so any time I've seen her since -- which isn't often as she lives on the other side of the country -- it's been a bit awkward. But 2 thumbs up, a highly recommended experience for any young guy. It is a bit of a comment about chicks and their morality but that was none of my concern.

And yes 25 YO is hardly a cougar but she could have been 35 or 45 and it would have been the same experience from my POV.

Pros: PatMatronage with benefits.

Cons: You are learning how to please her, not the woman you're going to make babies with.
