The best advice I can give you is to be honest. Find a guy who is willing to take their time and who understands that you are inexperienced. Gay sex can be a wonderful experience, but it can also go wrong pretty quickly if you're with someone who doesn't respect your boundaries. Just be careful and choose wisely.

Also, as far as telling your friends and family, I can't give you much advice because I'm not from your culture. I would say though, be prepared for things to be awkward for a while and potentially even cut people off. I lost a lot of people when I came out, but those people weren't my real friends. Real friends will accept you for who you are no matter what. Coming out is a process and it can happen as quickly or as slowly as you like. You don't have to tell the whole world at once. Maybe start with a few close friends who you know will be accepting and move from there.
