is it ok to go on a date with someone you had a one nighter with years ago?

Like well over 10 years ago i got introduced to this guy and I found him really attractive but neither of us were wanting anything serious. We had a one night stand. Then we hooked up again about a year later. 
Well we are both in our 30s now, both had unsuccessful relationships both been single a long time. He's moved to Australia but he's moving back. Do u think I should date him or just keep it as a sex FWB thing?
