Daughter doesn't want me to tell my husband she has a boyfriend

My daughter is about to be 17 and recently started dating someone. I have not met him yet. He's actually one of my son's friends from his school and math and science club. My son is 15 and goes to a different school than my daughter. He goes to a school for autism. My son is verbal. He wasn't when he started 10 years ago (school is for ages 4-18) and there are all different people across the autism spectrum but they may struggle in a regular school setting. My daughter met him when I went to their little science fair. She is begging me not to tell my husband because he can be a little much sometimes and almost like he's trying to scare boys away. He means well. He just cares about her and thinks all boys want one thing. She just doesn't want her dad to ruin it, especially since this person she's with already struggles in social situations. Realistically I would hope my husband would go easy on him because we have an autistic son, but I know my husband and he could care less and thinks everyone just wants to get our daughter pregnant. I don't like lying to my husband though.
