Help a bro out here please! 🙏

Problem/Goal: My gf never experienced orgasm her whole life and I want our sex to feel better for her. The problem is I cannot do foreplays that much. Ayaw nya magpakain. Reason is kadiri daw kasi madumi yung private parts ng babae. I don't really care that much about that but she does and I respect that. Daliri lang gusto nya and everytime I play with her clit, di sya comfy kasi nakakakiliti daw. Di daw sya naa-arouse.

Context: My GF (F23) never masturbated her whole life. We're also each other's first. We are almost 3 years in the relationship and we've also done the deed multiple times but as stated above, I never succeeded in making her cum.

Previous attemps: I do foreplays naman. Playing with her boobs, kissing her body, using my fingers. Tried clit stimulation but again, she feels uncomfy daw doing it. I might be doing it wrong so I don't know. We've also tried multiple positions. I can last minimun of 30 mins naman at times doing penetration in different positions pero no good pa din. I've also tried to ask for her kinks kaso vanilla din talaga since di naman nga sya nag-explore. More on sub lang din sya.

Any girls out there who has the same experience as my gf? Am I playing her clit wrong? Again, she's also my first in everything that's why I don't have any clue on what to do.
