WIBTA if I don’t tell my boyfriend I did OF??

I was an OF model between 2021 and 2023. The content I posted was always "single girl next door", with no partners involved, because I’m not the type of person to involve others in that for money. I’ve been in a beautiful relationship with my boyfriend for four months, and he seems like the kind of person I could have a great long-term relationship with. However, I’ve overheard his conversations with his friends about OF models, and his opinion of women in that line of work isn’t positive. He even stated that he couldn’t have a serious, lasting relationship with someone who’s an OF model.

I wanted to tell him the truth, but now I’m afraid that if I do, he’ll lose respect for me. I’m not scared he’ll break up with me, because he’s a wonderful guy who genuinely cares about me, but I fear that his respect for me will fade. I’ve decided to wait another 2-3 months and see how things progress between us, but I can’t sleep at night thinking about whether I’ll have to keep this part of my past a secret or tell him the truth and risk losing his respect. I don’t like lying or hiding things that could hurt the people around me, but I also don’t want to lose him.

I made certain decisions when I was 18 and had to support myself somehow. I’m fully aware that I’ll have to live with those decisions now, but I’m scared they’ll come back to haunt me.

Has anyone here been in a similar situation? How did you handle it? What was the outcome?
