I’ve found it surprisingly easy to talk about things like puberty and sexual questions online with new friends from the US and UK on Teen forum. Everyone shares quite openly about topics like penis size, erections, and masturbation. It feels different from real life, where people seem more reserved about vulnerable topics. I haven’t met anyone in person who talks about depression, for example, and it often feels like people hide their true feelings. Perhaps the anonymity of the internet makes it easier to be open in some ways.
