Sex and BJ help

Samira
I'm headed to see my Boyfriend who's at college. Im going to stay with him for a week or however long and I will say that after months of not seeing him, I am definitely ready to get him naked again. 
Two problems though:
1.) Sex hurts for me. I don't know if it's from not being aroused enough or what. I know I want it in the beginning at least, really bad. But even from putting the tip in, it just hurts and kills my mood. Blah. Any idea what's wrong with me on that front? 
2.) I absolutely hate the taste of cum. I wish I could be like those girls who say it tastes sweet and they love it, but I can't lol. And to make matters worse, I love going down on him. Any tips on how to kill my taste buds for a little bit? I know I could get let him pull out and spray wherever, but I am determined to swallow at least once just to know how it is.
