Might this be a sign my husband is secret gay?

Its not at all uncommon for my husband to 'finish' before i 'finish'. We dont worry about condoms because I had a teen abortion that ruined my body. The other night he was 'finishing' inside me and I was kind of annoyed cause i hadn't 'finished' yet. My husband said he would make good on it and 'finish' me another way. He performed oral cunnilingus. The disgusting part is that he had just 'finished' in there like 20 seconds earlier so his stuff was still sopping up. I know for a fact he had mouth contact with his stuff because it was very obvious. I just laid there trying not to be disgusted and told him it was no biggie but he kept going then went to sleep in his chair. I just laid there all night wondering what I just took part in. We haven't talked about it since. This was recent.
