Can’t seem to orgasm anymore

So I’ve been having this problem where my orgasm seem to have turned off for lack of better words. I used to be able to reach orgasm via penetration but, for the last couple of months, I can’t. I can only orgasm through oral. The only thing that I’ve been doing with penetration is squirting a lot. What is going on? My boyfriend feels bad or that I’m being let down because I can’t.
