PH off?

Soooo, me and my boyfriend have been together for almost 9 years so the comfortable level is extremely high. So he’ll tell me if my vagina has a smell to it. But I feel like it doesn’t, like yes it smells different at times but I believe that to be cause of me getting off my period or him being a smoker and eating unhealthy and always ejaculating in me lol and it’s never a fishy smell. I honestly love the smell of my vagina no matter what lol. I’m just insecure because he has said hurtful things like that in an arguement. Has your partner ever done that? Also he always wants oral from me but he claims he doesn’t like giving (he has plenty of times). I hate that so much.
