sensitive topic - internet searches

[belay]

DS (13) had a day at school recently where they discussed some sensitive topics around sex and relationships.
I looked at his internet search history and today he has typed in "naked woman/sex/ rape"/"when is the best time to rape someone". I am horrified and not sure how to approach this with him. He hasn't been able to access anything due to parental control in his phone. Is this him being curious after it being discussed at school? Never had an issue with this before. He's also sent an inappropriate text message to a slightly younger member of the family. I just don't know what to do

How about watching the Thames Valley Police's Consent video together and making sure he understands the analogy between cup of tea and sex every time.
