<human>: I've been dating this girl who lives in my dorm, a few floors up, for a couple weeks now.  She is, by a fair margin, the most attractive girl I've ever dated (my friends and parents had no problem going "Whoa!  She's defnitely not like [insert ex-girlfriend of charliedayman's]") and I get fairly turned on just being around her.  Suffice to say we got pretty physical pretty fast.  However, we also have just hung out without doing any hooking up quite a few times, talking about music, likes and dislikes, etc. (I think reddit would like her a lot because on our first date we went to a showing of "Monty Python and the Holy Grail" at her suggestion).

I had a conversation with a friend today that made me worry, though.  I went up to her room late last night when I was still up with friends and she just got back from celebrating her friend's birthday.  We hooked up for about an hour and then cuddled for another hour.  While we were cuddling, I felt myself compelled to tell her "I love you" even though I don't think that's true yet.  I told my admittedly conservative friend that I kept wanting to tell her I love her even though it's not true and he told me that's because my relationship with her is purely physical.  Is that compulsion actually a signal of that?  If so, what can I do about it, considering this girl and I both want a strong relationship?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I keep wanting to tell my girlfriend I love her while cuddling, does this mean our relationship is mostly physical?
