I'm 16 yrs old effeminate gay guy i ended up sleeping with a 25 year old he never called me back now?

well i thought this guy was really decent and nice and stuff he was very rich handsome and all could hold up a good conversation he said he'd be in contact even after sex although i wasnt really hoping a long term relation i wasn't looking for a one night stand either he said he'd come back(Atleast for sex) its been 3 days he never called me back,didnt reply to my messages i was stupid to give into the temptations now i can't stop thing about this man he was soo good to me i still feel him how do i forget this guy,he was the perfect boyfriend i could ever have. :(
