Dirty Talk

So I'm currently away from my fwb and he likes to talk dirty to me over the phone and Skype. I on the other hand am more comfortable doing it in person. I've told him this many times but he still tried getting me to do it. He finally gave up and hung up the phone cause he has work tomorrow and although he didn't say it I know he's disappointed/upset. I don't know why but I feel so bad and embarassed. I don't know what to do!
