I think my girlfriend (32f) believes she’s adventurous in bed. I (34M) do not.

I’ve been dating my current girlfriend for about five months now. When we first started having sex, she described herself to me as a “very sexual person,” which was an encouraging sign. She would text me things like “I want you in all of my holes.” I thought she surely had some kink to her. However, since then, I’ve found myself fairly underwhelmed by our sex life. It’s mostly made up of missionary, doggy, and me going down on her. It is always in the bedroom, on the bed, essentially the same every time. She will get on top or go down on me if I specifically ask her to, but doesn’t seem into the idea when I ask and so it’s not particularly enjoyable as it’s so one sided. I get her off at least once through oral every single time we have sex and her satisfaction is important to me. By all accounts, she is very satisfied. I am not.

Last week I tried to break the cycle a bit by introducing her to an online quiz that both people take, and it asks specific questions about things you’d like to try in bed. At the end, it only tells you both what you said yes to. I said yes to 95% of the questions- from light bondage to analingus to pegging and everything in between. I was hopeful to find a few hidden kinks of hers, but she never ended up finishing it, saying it was too long and that some of the questions freaked her out. (In her defense, that question was “do you want a gun or knife pointed at you during sex.” Haha.)

I also bought a few sex toys to try and introduce. She enjoys having her nipples played with and lightly bitten, so I bought some fairly innocuous nipple clamps for her. They look more like jewelry and were not clothespin style bondage clamps or anything scary. They are also adjustable so it isn’t painful. I introduced these during sex a few weeks ago after we’d both had a few drinks and she responded with basically “what the hell, no way.” So I’m having trouble even pushing her own kinks even an inch.

This woman is very sensitive to criticism and I know I need to be very delicate in my approach. Flat out communicating I’m unsatisfied will shut her down and make her feel awful, so that’s not a great option. But I know that long term this is going to be an unsatisfying sexual relationship for me. I already find myself going back to porn to indulge that side of me and it’s not something I’d like to do. Porn ruined my previous marriage and I don’t want to go back to it.

Anyway, I’m looking for any suggestions on how to handle the situation. I’m still hopeful that I can get her to be a bit more open minded... just running out of ideas. Am I expecting too much five months in?

Tl;dr My girlfriend lacks any sexual adventurousness and I need more to be satisfied.
