Accusation

Help please someone I have noone to talk to and I need to hear some sort of words.... ok today lately me and the fiance has been going at it all the time. Well today was our engagement photos. We nade it thru and they were beautiful well since we have been going thru it we havent been active. So when we got to the house I went down on him and we hot busy. Well my menstrual is about to start and I get pain when having sex so I stated slow up. Anywho we finished. As soon as he was done he states when I get off wr are going to have a long talk because their is no reason your vagina should smell and taste like lambskin condom. I am so lost I have never cheated on him and he was very adamant about this. What are you guys thoughts? This is the second time he has done this when I randomly give head what do I think?
