<human>: Can you summarize the given text in a few sentences?

Throwaway for obvious reasons. 

So my girlfriend and I have been having sex for the last 3 months now, and we have been together for about 7. There is just one issue I am concerned/worried about, I have no problem going down on her and making her orgasm with just my hands. But she has not once given me oral sex, nor has she given me a handjob. I am not complaining since the sex is absolutely fantastic, but I am concerned that she might be quite paranoid or afraid of something specific which I have no idea what it could be. I have mentioned oral sex to her in a jokingly manor before, and she replied with 'maybe one day'.. I kind of left things like that since then.
 Looking for advice on how to approach her about it.
<bot>: Gf hasn't never given me a handjob nor oral sex despite the fact we have been having actual sex for the past 3 months.
