[Forget About Her]

I've been seeing this great girl for about 4.5 months. We are both work full time, and take a few classes at university. We both have our own places and are working on getting established in life. (I'm 23, she's 19)

At first it was great. We dated a lot, went out on the motorcycle, dinners, etc. The sex has been unbelievable, with the exception of the occasional pre-mature finish on my part. She spends the night at my house 3-4 nights per week, has a toothbrush at my place, etc. I like her a lot, but i'm noticing some differences now.

I'm starting to find myself less physically attracted to her. Don't get me wrong, she is a very cute girl, is not overweight or anything like that, but she's just really not physically the type of girl I usually go for. I've been having more episodes of some 'pre-mature release' lately, and accompany that with the fact I don't find her all that physically intriguing, I haven't been as excited to have sex with her over the past couple of weeks. She loves it and wants it all the time, and I just find myself just wanting to 'chill' with her rather than have sex.

I really like her, and i love her personality and don't want to break up with her, but is there anything I can do? Does anyone have any input on this at all?
