Porsha Williams hit the beach in Hawaii, showing off her bikini-devouring body -- and it might be more than her guy friend can handle.

"The Real Housewives of Atlanta" star was splashing around and taking selfies with the guy, while sucking down pineapple drinks. Sources close to Porsha tell us her sand mate's name is Todd, and they're celebrating his 40th birthday.

We're told they've been friends for years, but she's dating these days ... so, sounds like he's got a shot ... IF he can hang with all that booty.
