I just wanted to say that I swallow my boyfriends cum. I actually think it would be more gross to spit it out. Then it's in your mouth longer and you see it. At least when you swallow it's down like a shot and that's that. It's also my choice.
The only time my throat has ever hurt after giving a bj, is when I've taken him deeper than normal. I would hazard a guess that this is what you did. Hell, I've had whiplash AND a sore throat, at the same time, from it... LOL So, don't worry about it... Or you're getting sick... But, that wouldn't be from the bj...
Girls need to seriously stop worrying about so much shit... and just sit back and enjoy it more... There's nothing wrong with cum, swallowing cum, or enjoying it. Lol.
