Caught by uncle

i was having phone sex with a guy on the phone once. uncle walked in my room. saw what was going on and closed the door.
i was so embarrassed. i didnt know what to say. i avoided him. finally i apologize to him for doing that. he told me that i had nothing to be sorry about. most guys do it...even he did. he said it was healthy but i shouldnt do it to often. he asked me who i was talking to. i wasnt going to tell him the truth but i did. he asked me if i was gay. i told him i wasnt sure but that i had been with guys before. he just said be careful & lock my door next time, and he hugged me. we never talked about it again.
