Ds is year 10 and has had a gf for about a year. Theyre both shy, quiet types, (she has bad anxiety) but he does come to me with his worries. He's disclosed that they are experimenting sexually and panicked because he ejaculated close to her vulva. I reassured him that pregnancy is unlikely, but in the future it is not worth the risk or worry and to use condoms when intimate, even if they are not ready for full sex. I reiterated that there is no pressure. He wasn't sure how to get condoms, unsure if he was allowed to buy them. I explained how/where they can be obtained, and also said I would buy some, as I'd rather he was safe.
I told my partner (not DS's Dad - we are divorced) and partner told me very bluntly that if I buy condoms I am giving them the green light for sex and what a bad idea this us as they are immature and not ready to handle any consequences. If it's relevant, partner has no kids of his own.
How should I handle DS's disclosure? Continue with the safe sex message and practical help to get contraceptives; or as partner thinks, try and steer him away from gf? I was really confident in my response until partenr challenged me, now I'm not so sure. Thoughts, please 🙏
