Questions: Guy's Behavior

My girlfriend had a 1 year relationship before me and the ex was her first sexual partner. She did oral with him and had intercourse once. Since she chose him first and made him the first sexual partner, I feel that he is the ideal prototype guy she likes and now I'm always comparing myself to him and trying to be better than him.

She has never implied or said that he's better. She says I'm better looking, treat her much better, better in bed, happier with me, and better all around. However, I'm tan skinned and muscular and he is White, average looking, and not muscular. We are 2 totally different looking people.

She is not my first girlfriend. She is actually my 10th girfriend and my 9th sexual partner (if you count mutual oral sex as a partner). We were strangers. I never knew she existed until i met her.

Even though I never knew she existed and she never knew I existed, Still Chose Him First, made him the first sexual partner, and made him the first to conquer. Therefore, I feel like a last resort. SHE CHOSE ME SECOND. I AM HER SECOND NOT HER FIRST. However, she is beautiful and other guys have shown interest in her.

Should I be competing with an Ex she no longer has contact with? Should I work hard to beat the ex in every aspect. Or, Should I just be myself because that is why she is attracted to me to begin with and why she chooses me now. I just wanted to be 1 first one chosed from the start.

I like listing to love songs. Not because i'm trying to impress a girl by pretending to like it, i just do like them. I like to listen to a love song and imagine myself in a loveing relationship as described by the song.
Is it weird that i am a guy who likes love songs?
Guys do any of you like love songs?
Girls do you like it when a guy likes love songs.
