TIFU by thinking my son was having gay sex when he was just eating Hummus

So I (39F) have a son (15M) and he brought a friend round today.

They immediately went to their room and I assumed they would just play some video games or whatever so I was totally fine leaving them.

It was about 30 minutes in when I was walking past, I heard sounds such as 'Omg that's so good' and 'Its so good with that in it' and various 'mmmm' sounds.

It really sounded like they were having gay sex, I was super weirded out by it so I quickly went downstairs and waited for his friend to leave. When this friend left an hour or two later I asked my son what they were doing in his room (because although I don't mind him being gay, and ik it's normal for teenagers to have sex, a condom really should be used) so I planned to confront him about that.

However the answer shocked me to my very core. They weren't having sex, they were eating hummus.

I was shocked, and initially didn't believe it. We had never had hummus before and I asked him to show me the hummus if this was true. So he did, and I ate hummus for the first time, and oh my god was it good. We experimented with different things in it like bread and carrots and it was great. Apparently his friend had heard about how he had never had hummus before and thought this was absurd so had planned a date for a hummus party.

So yeah, it ended up being quite a good ending, i discovered how nice hummus was.

TLDR: Thought my son was having gay sex, he just really liked hummus.
