anyone else? (kind of detailed...)

So lately i have been noticing that my boyfriend has been acting weird during sex. One time i looked back behind me and saw him watching tv while we were "busy" :/ . And lately he just wants to start fast and all.  Barely wants to even kiss , the problem with him wanting to do that so fast Is that i don't have any time to get aroused , with realy hurts when we realy start to get busy. 
I am wondering if there are people with the kind of the same problem and what you did about it
(Ps i tried talking to him about it but he always gets an attitude about it saying i just don't want to have sex with is not the case so i have no clue how to handle this)
