Most of the time people say they don't like anal because it's taboo and they've never actually tried it. To echo what others have said, anal is pretty good if done right. Always make sure you use plenty of lubrication (that warming KY stuff works well), work your way in VERY slowly and gradually, to give her time to adjust and minimize pain. Also you should stimulate her clit (or have her stimulate herself) while you are doing it to give her something else to focus on, because anal is much more pleasurable for the guy than it is for the girl. Once you've gotten all the way in and she's gotten used to it, you can begin to speed up your movement. Be very careful though, as it's going to be very tight and feel really good, and it makes holding your load considerably more challenging. The girls I've done it with told me afterward that it was strangely stimulating for them, but they needed a little extra "distraction" like fingering or massaging the clit to get real enjoyment from it.
tl;dr don't knock anal or say it weirds you out until you've TRIED it, and more than once at that. Using one experience to judge it is silly.
As far as normal sex goes, I've come to realize that sex actually gets better the more times you do it with the same person. When you have sex with a person you've never done it with before, you have no knowledge of what they like/don't like so the entire thing is an awkward, sloppy "feeling out" process (no pun intended). It takes a few times to really get in sync with one another, which is why I'm not a big fan of one night stands. They sound great in theory, but in execution they end up being underwhelming and awkward.
Once you've gotten to know (pun intended) a person well enough you get to know their hot buttons and what really makes them tick in bed. This improves the sex vastly and you have less occurrences of "meh, I've had better". Also, having emotional feelings toward the person makes everything better in bed. To be absolutely corny for a second, I will tell you that nothing compares to that moment when you're in bed with the woman you love and your eyes lock. I hope everyone here gets to experience that as I have.]
Finally, whatever you do, DO NOT burn yourself out by having sex all day errday with a person when you start a new relationship. I know you're going to want to because it's new and exciting, but I promise you will get bored and the relationship will end badly. If you pace yourselves, you won't get bored and the sex will be amazing for as long as you want it to be. This helps relationships remain healthy (obviously not the only factor, just a part of it) and the sex continues to improve.
Morals of the story: try anal more than once, one night stands are overrated, the more you have sex with the same person the more it improves, and pace yourself when you start a new relationship.
