Is it normal not to like blowjo*s??

Here is the deal people... Some time ago I had my first bj and, well, it didn't feel very "comfortable" in the other person's mouth. But, you know, I expected it to feel so much better! I thought that my penis would feel so much more of the "stuff" but it is almost hard to understand when she actually puts it in her mouth.
Not only that but after I came(which would happen very easily) Having it in her mouth would hurt so I would have to push her away. And at the time I came.. it didn't feel that good either. I could have finished anywhere else and it would have been the same.
Also sometimes even when she kisses on my skin on my lower body it feels kinda weird, like tickling but with a little pain maybe.

So, do I or her have a problem or is it just how things are? Could it be attributed to her not being very experienced or me having a hypersensitive skin??
