For girlies with bfs how did you tell them you read bl

I’ve been a weird kid who got too much freedom on the internet and stumbled across bl at a very young age.. it’s not that hard of a topic to talk to my friends who are girls although only a very very few people know.
I read lot of gay smut, fanfictions and follow gay ship artists online but irl I’m not the weird kiddo and I don’t spill about me reading hardcore smut when I get home. Although, I thought my bf knew me the best cause I had been open about my other weird interests and had no problems with it so when he mentioned it, I casually said yeah I read bl but he said “ew” and my heart dropped so I lied about saying I only read fluffs and no hardcore.

How do I soft launch to my bf that his gf is into reading about two dudes fuvking eachother.
Or do I just hide it for the whole relationship..
