Should I first have sex with a girl before telling my crush that I love her to ease the tension or not?
Yes you should definitely have sex first. Lets get real If sex is not good relationship either. Also why you want to do that? Let things flow...
Um, yeah, how about recovery focus as @MisterDirection has suggested? No, you should not have sex with someone else in order to feel comfortable with the person you really want to be with. No, you should not have sex first before telling her that you love her. I also think you need to do some soul searching about what "love" is to you. Peace, -Quinn
What? A crush that you haven't even dated? That's not love dude. NO Or, do you want to ruin your chance with her? Then yes, absolutely.
