densensitized clit and 🐱

I’ve been using a vibrator since I was 15-16 years old and now that I’m sexually active..My clit is desensitized...I have to rub for about 10-20 minutes to cum from rubbing my clit and I’ve only squirted once from head. It’s hard for me to orgasm from penetration too...every time I feel it coming...he changes positions or he cums and I don’t 😒...please help. I just want a man to make me cum. 😭 I’m tired of vibrating and fingering orgasms. How can I regain sensitivity in my clit and vagina? 😭
