My man told me he doesn’t wanna go down on me…

Ok so the other night my man and I were gettin a little freaky yk and I asked him to go down on me and then he started to but I was getting frustrated cuz he wasn’t on the right spot blah blah which then resulted in me getting more frustrated because I’ve been feeling like he doesn’t actually want to do anything for me like he use to. Then he ended up saying he hasn’t been wanting to because it doesn’t taste good. (Mind you a few months ago he said he CRAVED it and that it tasted good 🥲) this upset me rlly bad in the moment and so I started crying and just felt so embarrassed because he never told me that before and I didn’t know why it wouldn’t taste good anymore. So girlies pleaseee help im so embarrassed and idk what’s up. I wash the outside with unscented dove soap every time I shower (daily), I drink water, I don’t wear super tight thongs all the time idk what it is. ☹️☹️
