Yes
She does not swallow>
Yes. It's delicious and it'd be rude to spit.
Well i dont but i think you may need to see a doctor about that
Easy, one way to get a girl to swallow is after she gives you either a blow job or a hand job or even both as soon as your ready to ejaculate ask her to swallow and most likely she will. She'll be so obsessed with what's about to happen she won't really say anything till after. And most importantly DO NOT TELL YOUR FRIENDS THAT SHE SWALLOWED!
YES.
If you like egg-whites its easy... A: Just let the guy ejaculate in your mouth and swallow it. Or you could lick it up off yourself or someone else.
it is bad to swallow the hormons you could get sick
It's not dangerous unless he has a STD and it's up to each person what they want to do. There are no "should's". If you want to it is erotic to him when you swallow even to just to taste his ejaculate.
Yes you can.
NO
No, but it is a sign that the sex is bad.
It is completely harmless.
