If you draw a line, don't relent. Stick to your guns. Just like children, women push you to see your limits. What you will allow and not allow. (And if you let her get away with something, it's going to be harder the next time as you have now set a precedent.)
Don't EVER feel guilty for wanting sex. She has no problem asking me for a back rub... If you enjoy sex, then have sex.
Here's what happened:
I have a girl I've been seeing for almost 2 years now. We have been on and off a little, she tried to make me be exclusive with her a few times (once saying she was going to date someone else, which only worked out for a month before she came back).
She called me last night to come over, we went for a drive, came back and had sex.
"Wanna go for breakfast tomorrow?" were her words as she fell asleep. The next morning we woke up and I started kissing her, but she kept rolling away for me to spoon her.
She says, "Let's go for breakfast!" I smiled and told her I can't get up before morning sex.
She says, "You can't just use me for sex."
I said ok and rolled over and was just going to go back to sleep.
She puts her clothes on and goes to leave. "I'm leaving, ok?"
"Ok, have a great day."
I get up, make my bed and started thinking if I did the right thing.
Shit, am I being childish? No no, just stick to your guns. So I did.
Not 5 minutes later, the door opens and she comes storming in. Jumps on me, demands that I fuck her. "I like your attitude." I told her.
So we fuck then go for breakfast. The whole time, she's carrying conversation, pays for breakfast, grabs my hand as we walk out.
She just dropped me off. Standing my ground has definitely increased attraction considerably.
Thanks TRP, it's times like this that I enjoy having you all as a frame of reference for myself. "Would TRP condone going running after some girl and reason with her to come upstairs and have sex with you?" No, they would tell you to maintain frame.
