<human>: Just a little background information, my boyfriend and I have always been sexually pleased in our relationship. He always made sure I was okay and did his best to make me comfortable and happy, as did I to him. This has worked wonderfully for both of us. I had no complaints until recently. 

Within the past couple of weeks I've felt like everything has been about him. He is always asking for me to blow him and make him come, obviously I oblige without expecting anything in return, however every once and a while I like to get a little something in return. Lately he hasn't been doing much to bring me to climax which is a problem for me. Last night I was left again unfinished as he just rolled over and fell asleep. 

This afternoon I had brought it up because he was asking me what was wrong. So I told him I felt like he wasn't trying as hard as I was to please me and that it would be nice to climax. That I felt like he didn't want to treat me. I think he took it as an insult. As if I was saying he wasn't good in bed or something like that. Usually we have no problem talking about misunderstandings in our relationship, because shit happens obviously. But after 15 quiet minutes I asked him if we could talk about it and he just walked out. 

I honestly don't know how to approach him right now. I don't want to hurt his feelings or make him feel like he isn't any good, because that's not true. I just feel less sexual pleasure and it's frustrating. Any advice?

Can you give me a shortened version of the text?
<bot>: Told my boyfriend I was sexually frustrated and now he won't talk to me about it. How can I talk to him about it without hurting his ego/feelings?
