How do I get my girlfriend to RE-start having sex again?

I have been questioning myself serveral times in the past two-three weeks, to why my girlfriend, after 20 months does not want to have sex anymore.

Our relationship has been fantastic, I love her with all my heart, but it fustrates me that we don’t have sex anymore.

In the past we were extremely sexual, having sex anywhere and any time of the day/night. To sum it up. there’s 7 days in a week, we did it 5-10 times depending when we were able to see each other. Not one week past without sex.

but its been almost 2-3 months without any. I know sex is not everything. I love just spending time with her and making her laugh. and seeing her smile and just holding her.

But this “ drought” is questioning my method.

Is she simply bored? Is she not satisfied? Is she not attracted to me?

I try making a move, but she always pulls away and gives me this look. Like…What are you doing? I try touching her arm and just slowly rub it and make my way to her breast, while kissing her… and then she pulls away and says she doesnt like being rubbed…” its bothers me”

But then. its as if she likes to see me suffer… teasing me and bouncing her boobs in front of me and slapping her ass when she walks away… and knowing I can’t do anything because were in a public place.

I don’t know what to do… I’ve’e tried talking to her, and she tells me she feels the same way. And then puts me on the guilt trip, by saying I’m such a bad girlfriend. And even told me “ maybe I dont pleasure you enough” but then its I love you , I love you and I know she does… without a dought.

Can someone help my situation? or give some advice? I would really appreaciate It.
