Advice please. I'm a female and found my boyfriend's X account following a lot if explicit gay content

Loving relationship of 6 years with one toddler and baby on the way please be kind.

Never suspected my boyfriend of being gay or bi in any way but was on his phone when a twitter notification popped up and turns out he has a secret account following strictly gay explicit content creators.

We have an extremely active sex life, he seems to love my boobs and is always giving me oral but he is also looking at dicks on twitter? Help me make it make sense please
