Well I believe there's a way to hit on girls before a relationship starts:
My friend is very nice..... and you know what? You too!
This kind of compliment is used before a relationship starts.
After the relationship starts these ones can be used:
Oh how my arms are needing to hold you tight, my hands long to run up and down your body and my heart in need of your love!
I love you so much baby! Everyday I love you a little bit more. I can't wait to have another weekend like that with you agian. I hope really soon!
I wanna learn more of them (the two kinds) but I don't know how.
Can you guys give me some help??
The greater your vocabulary, the clearer your expression.
