I don't know

What to believe, im married with a man and We have a 5 month old , married for 2 years together for 3 , After I got married I told my husband I'm bisexual but he thought I'm kidding and he was more like I don't like that so I said right away haha i was kidding cuz his reaction was weird and I didn't want him to change his opinion about me or I don't know, but the thing is I should tell him again or I just let this go ? - he knows about me kissing touching with another girl when I was 15 but I lied when he asked me if I liked, I said no but I did like it ****** I'm not planning to leave my husband, we are happy, I wish to not lied to him but I can't go back in time and fix the problem
