Sex...guilt trips?

Hi everyone-

I will first start off by saying that I have a bit of an anxiety problem, so these questions may seem completely irrational to some of you. Please bear with me... sometimes I just need another opinion.

Anyway, have any of you experienced (given/received) any form of guilt tripping when it comes to sex? And when does it cross the line from expressing your wants/needs/concerns to a guilt trip?

Here are two scenarios: when SO and I first starting dating, (had not had sex) we were fooling around and he basically asked me if I was going to go down on him. I told him I didn't know, because I had never ahem, "not spit it out" before and I didn't know if he was expecting that. So he replied, "Ok, I guess I can go to into the bathroom." Sounded sad and disappointed. I assume implying that if I didn't do it, he would go finish himself. I kind of took it like, "i GUESS i can go the bathroom if you WON'T." Second scenario: I have told SO in the past that I felt like I had been doing a lot more sexually for him than I was getting (not sure if that was true, but how I felt). Specifically with oral sex. I asked, when will it be my turn? Or, I've given you many O's, am I going to get some too? Seems immature looking back.

Anyway, do you think things like this really bad? These things don't happen now that our relationship is much more mature, but I feel guilty for ever trying to pressure him. I feel bad if he was trying to pressure me. I don't know if that is even the case. Should I be worked up about this or does this seem commonplace? Any thoughts?
