Not to suggest I haven't learned stuff from asking, but I think I've learned more by answering. I put myself in the situation and think "I'd do that if I liked a girl", "I wouldn't be creeped out by a girl saying this", "I'd love it if a girl did this for me", etc.
I've learned a lot by answering. People ask all kinds of different questions and I try to give them honest advice based off of my experience. At all ages, we are curious and doubt our selves as well. Life and relationships are complicated. When I answer other peoples questions things seem so easy and I am able to "practice what I preach" but sometimes it seems harder to do that. Relationships/feelings are so emotion based that we do not always stop to think rationally when it is subjective. By thinking and reflecting, we are all human, it puts me in a better mindset of how to handle things and to remind myself of all that I have learned along the way. This is a good site for supporting people also. It's a great way to blog with people who have no alternative or vested interest and will give you the best advice that they know how.
