How do I (28m) get my girlfriend (26f) to do sexier acts in the bedroom?

I have a girlfriend of 3 years. We have lived together for 3 years now as well.<br><br>She's a great girl. Everything about her is perfect. I'm really lucky to have her in my life.<br><br>I was a virgin until 22. I hooked up with 2 girls when I was 22 and I got some sexual experience. I then started dating more and had a few girlfriends. I was always the type to be very private about our sex. I never told my family or any of my close guy friends if the girl I was dating was good in bed or not. I'm not the type to talk about that kind of stuff.<br><br>So my current girlfriend, we've been together for 3 years now. She was a virgin when we first met. I was her first. I knew that she was a virgin when I met her.<br><br>I'm not trying to shame her or make her feel bad about herself. I love her.<br><br>But when we have sex with her, I feel like she just lies there and does nothing. I'm the one doing all of the work like kissing etc.<br><br>She doesn't have many kinks at all.<br><br>I've brought it up to her a few times but every time I bring it up, she just gets upset and tells me to stop. I've brought it up a few times and we had a huge fight. She told me that she wants to be more adventurous in the bedroom but she feels self conscious about the idea of talking about kinks. I told her that I like a bit of light choking and she told me that she felt uncomfortable doing that.<br><br>I told her about how I used to hook up and she got upset at me as well.<br><br>Everytime I bring it up she just feels self conscious about herself. She asks me if I like her body or not.<br><br>I do! I absolutely love her body. That's why I want to have sex with her more. But she doesn't have much of a sex drive at all. Even turned down the idea of having a threesome with her and another girl.<br><br>I don't know what to do. I really do love her but I feel like she doesn't fulfill my needs in the bedroom. And if I bring it up she just feels self conscious about herself.<br><br>Edit: I've suggested buying lingerie and she said "why?". I asked if she can do certain acts like oral and she just laughs and tells me to stop.
