Is it normal or not

Does she like that you call her vagina a "down part?"

The not enjoying kissing part would be a dealbreaker for me.

I bet your girlfriend also doesn't like exactly the same food and music as you do, and she doesn't laugh at some jokes you find hilarious. People have different preferences. That's just the way it is.

As for why she has those preferences, who knows? She may have enough insight to understand why she dislikes those things and she may trust you enough to explain someday, or she might never understand herself.

The big question is whether the two of you are happy with the sexual relationship you have and if you can accept the differences between you. I was married to a woman for more than twenty years who had a real hang-up about her vagina. The sexual side of our relationship was good, but she could never get into me giving her oral. That was based in some early sexual trauma which she never managed to get past. I always thought her inhibitions prevented her from experiencing something enjoyable, but she was satisfied with manual and penetrative sex, and I accepted her choice.

I dated a girl be like that, I did go down on her once, only afterwards she said she doesn't get anything out of being eaten out. She also refused to give oral. It was only penetration with her in missionary position. She was also the only woman I ever slept with who wore a bra to bed. It would come off for sex only to her putting in it back on to go to sleep.

I think she wants just penatration just so you can get off,it sounds to me like she's not really into you

Ask her why if you don't understand :0
