DS is almost 16, his girlfriend is almost 15. They're both autistic and attend a SEN school so are in the same class (it's about ability so the ages are mixed) but if they were in a mainstream he'd be Y11, she’d be Y10.
They've been in a relationship for about 2 years although its been just holding hands for majority of it, just before Christmas DS told me they'd kissed. DS is mentally about 13 and the girl probably is too.
Recently, he did search up porn which did get blocked so he didn't watch any of it, I assume he heard it at school and was curious as to what it was so decided to search it.
Earlier today, he asked my older son for condoms, which he didn't give to him and told me about. I've spoken to DS and he said they're ready to have sex and wanted to use a condom like id told him.
Luckily the girl is away for a few days but how do I approach this, when she comes over here they're in the living room but when they're at her house I know her parents let them go to her room and leaves them with just her older sibling.
WIBU to say he's not to go over there with her and to only bring her here?
