No longer a virgin....what can I expect?

Lyric

Sooo I have gone 21 (almost 22) years being a virgin. I just hadn't ever found the right guy. Well I found the right guy and we had sex for the first time last night. First of all it was AMAZING! And I can't believe that I was missing out on all that! But now I'm looking for some advice on what to look out for? Is there anything that I should pay close attention to the next few days? In case something is wrong?

Thanks in advance!
