Can’t Orgasm??

My bf and I have been together for almost a year. Around May is when we actually started getting sexual with each other (me giving him handjobs, blowjobs)

Recently he’s been wanting to pleasure me, but I’ve been too afraid to let him near my vagina due to lack of sex education. Every time he tries to finger me, I can’t orgasm or feel any pleasure.

Tonight he tried giving me head after trying to finger me, but I couldn’t feel anything. I felt ashamed that I couldn’t receive any pleasure and I’m starting to think somethings wrong with me.

I’ve never masturbated cause I never was interested in it and due to lack of privacy in my house. Is there something wrong with me? Could anyone give me some tips on this as well?
