If you don't know the answer to a topic either look it up before replying or don't reply at all. Don't tell a girl that she could be pregnant through 3 layers of clothing. Sperm can potentially die when outside of the body  unless it's in particular conditions, for example a hot tub or vagina. Please don't go scaring girls because you aren't knowledgable in the subject. Yes the girls asking need to educate themselves more on how babies are made but at least they aren't having sex. Your comments could completely terrify and so if you don't know the answer don't comment. And sure as hell don't knock other people because you think you're right! It's very frustrating...!
