I can’t orgasm or Get Wet. Help!!

So I’ve only started recently become more sexually active without penetration. in 2021 I was fingered for the first time and I was not able to orgasm but I did self lubricate a lot. as of the course of 2022 I got more involved with sexual activity without the penetration I got eaten out for the first time and I orgasm but that was back in February now it is September and I cannot even get wet from masturbating and don’t know how to masturbate or orgasm I have tried pornography and tried going solo with no visual prompts but nothing does it for me I can’t even get wet I am scared that when I do eventually see my boyfriend he will not be able to get me wet. I have tried to orgasm by myself but I just don’t know how. I also fingered myself last night and I woke up to brown blood. maybe I’m just not good at sexual stuff I need help anyone with advice especially with the getting wet thing. I’m 19.
