No matter how old you are, when you're in a relationship and sex hasn't been introduced yet, life is carefree and beautiful. The lead up to sex is probably one of the most exciting stages in the relationship because you're both anticipating what it'll be like, flirting with the idea of it, and you're so attracted to the other person that you're certain it's going to be the best sex of your life. Except it might have been a while since you last had sex and you're a bit nervous about your performance abilities. You've never really had any complaints in that department before but you're still a bit worried that they might not enjoy your sexy time. What if they get into your room and see your teddy bear and think that you're a bit weird? What if something goes wrong? You've heard stories of their penis sort of breaking... what if you bounce the wrong way and you never see him again? What if you're trying too hard to be sexy and it turns him off? If he doesn't kiss you during, is he just there for the sex? What if it ruins everything? Sex complicates things so unless you're both ready, then try not to think too much into it, otherwise you won't enjoy it and if you start crying after, they're not going to take that as a good sign.
