Tonight we had a rare night completely alone and because we are both leaving town soon tonight was the last night we had together for the next 9 days. One thing led to another and he decided he wanted a blowjob and to finish on my chest, which is probably the hottest things ever IMO and I've wanted to try it forever. As he got close I could tell that he wasn't really enjoying it, he seemed preoccupied and frustrated. Although I had no problem spending a few extra minutes on him, he eventually pulled away and told me that it just wasn't going to happen tonight. I did my best to assure him that I understood and that instead we could do other things. My orgasms are difficult to achieve most of the time so I completely understood his frustration but he acted as if he had let me down. We took a break and ran to Starbucks and afterwards went back to his place and cuddled for a hour. Overall the night went well but I could tell he was slightly distant because of what had happened earlier. I'm sure this will eventually happen again, how do I handle it? Do I try and tell him its normal and it happens, or is that not what guys want to hear when they are having difficulty cumming?
