s/o experienced, not your 20 yr old friend
I’m gonna take this a little bit out of context. I can not emphasize how important it is not to discuss things with friends. Firstly, no one (I repeat, NO ONE), as happy as they may be for you, will not be a tiny bit jealous and that never brings good things. Secondly, usually a young girl (in this case a 20 year old) has a very distorted view of things that may or may not be potential problems. Choose a mentor that you trust, and someone with some measure of life experience. (generally 35+)
