Condom in his room

Idk where else to post this but I went to my bf house today and we were in the basement which is his brothers room because he had family upstairs or whatever . I seen a condom wrapper on the floor when I asked him about it he said it was his brothers ... but his brother lives in another state and the last time he was at his house was July 4th ... I picked up the empty condom wrapper and i touched inside of it and it was still wet ... so what should I think ???
