<human>: My current girlfriend is the only girl I've ever had penetrative sex to orgasm with. We've been having sex using the pull-out method, but the other week I got a little excited and didn't pull out in time. Now, even though she's on the pill, she insists on me using a condom. The problem is that I simply can't have an orgasm in a condom, I've never been able to, and I have rarely been able to stay hard long enough to put one on. 

This problem is made worse by her unwillingness to return oral sex. I go down on her frequently, usually multiple times in one night and then again in the morning for good measure, but she never returns the favor. I don't know if she has any particular reason other than perhaps it just grosses her out, but I feel like I'm being left hanging. 

So my current situation is that I can't get oral from my girlfriend, and I also can't keep it up while wearing a condom, so I'm left finishing myself off when she leaves. 

The condom thing is more important to me. I feel like this is a bigger issue, since I feel like I should be more aroused than I am, and seeing that most guys don't seem to have a problem maintaining and finishing with a condom. Is there a way for me to enhance my arousal, or make myself more sensitive? 

The oral thing is still important too, is it something that I should be able to just ask her about?

Give me the gist of the text in a nutshell
<bot>: can't keep it up in a condom, but girlfriend won't perform oral on me, so I'm not getting off even after I've gotten her off multiple times.
