I've been asked repeatedly this week so told my 7.5yr basics of sex. He knew that a man did something with a woman so I explained the anatomical implication, that it was fun but for grown ups, that it was okay to find it disgusting at 7 but one day he would be interested and a bit about consent/legality/age not always to have babies etc. What age did your children find out and how? Should I worry that he's going to explain to his 5yr old sibling before we get the chance? Does that matter? I am Curious as to other people's experiences and keen to know if there's anything specific I should add for safe guarding or other reasons? He didn't believe me at first and thought it sounded difficult to do (very sweet was relieved he was too alarmed although not enamoured).
