That's happened to me a few times, it was usually when my girlfriend was in an odd position. For instance, if she was laying down beside me and she doubled over to perform oral sex. I'm pretty sure in my situation it had to do with the way her mouth was rubbing against the head of my penis. See if you can get her to try a few different positions, see what works for you, maybe that'll help.
What is happening is that you are being turned on to a much greater extent by your girlfriend than what you are able to do by yourself. Pheromones and just plain "sparks" between you cause this increase. The increase reflects itself in the sensitivity of the nerves in the glans. (Don't you notice that your physical responses are off the scale when she is doing things to you and not nearly as high when you masturbate?)
This is certainly nothing bad, just use lube and less pressure if getting a hand job; if by oral, just use more saliva and less lip or tongue pressure. In fact if you think this is too much sensitivity, just wait until after you climax by whatever means she has chosen and your penis is too sensitive to touch at all for fifteen minutes or so. The cause for this is the release of hormones by the brain and is only temporary. Girls have this just before climaxing and guys just after.
An erect penis is always "sensitive." What are you asking?
i just want to know what the problem is when i get oral sex it feels to sensitive and i cant take it
