Question: i have been doingn sex with my gf 4 last 3 months but now she is not into it? 

Answer: If she is not into it, don't do it. If you are with her just for that, then you should leave her and find the girl you will be with for her, not for that. Try talking to her. Find out why she isn't into it. Maybe you will have to give it up for a bit.
