Sperm trouble

My boyfriend & I were having sex but decided to stop because we weren't using a condom. So we decide to go buy some & when we came back we continued. After we were done we cuddled for a while & he started touching my private area. But I noticed later that he had touched his dick when he took the condom off & his cum was all over it. Although he did clean it off is there a possibility it still went inside me? Can sperm still be alive if they're not in a wet area??
