Plan b

Meghan
So I had sex and now I'm just paranoid. I'm not in bc, but he used a condom. This is the first time I've really had sex, and I was just wondering are you supposed to feel like liquid (I guess cum?) when he is finished. I definetly felt liquid before he pulled out and I'm just trying to figure out if it's normal or if the condom had a hole and he didn't realize it.  I bought a plan b pill but I really don't want to take it because of the side effects. 
Edit- I really just don't even know what it feels like after sex so maybe I'm just being paranoid ? My friend said even with a condom you can sti feel it. Maybe it was from me ? It just felt like melted butter between my legs lol
