Me and my gf have been together for 1.5+ years now. It seems like the last few months are sex life has gotten very boring and redundant. Everytime we have sex it's the same thing. I have to initiate...normally I kiss and massage her alot, maybe go down on her for a bit depending on our moods, and then missionary position until we're finished. She doesn't really seem to put anything into it(although she always seems into it when the act is going on lol). She'll very rarely ever go down on me, and if she does normally 30 seconds later she's done. She's normally too "lazy". She doesn't wanna do doggystyle because she says it hurts...when just a few months ago she loved it. She doesn't wanna be on top because she says it hurts...when just a few months ago she said she never feels anything when she's on top. A couple months ago I tried standing sex with me lifting her and bouncing her on my cock...she loved it then, now doesn't wanna do it. I dunno, doesn't make any sense. It almost seems like she isn't into me anymore...but she's still always telling me now cute/beautiful I am and how much she loves me and wants to spend all our time together. I try bringing this up to her and she always acts offended...I dunno. Any ideas how to spice things up?
