Swallow all the time, everytime with my man because...
Unless he is wearing a condom to begin with I'm already tasting it.
When he goes down on me he doesn't keep spitting when the juices start flowing.
I read somewhere it helps fight acne
He consumes mass amounts of orange juice purely because it adds a slight citrus flavor.
Unless there are some serious funk issues it doesn't taste bad, just different.
Finally, if you trust him enough to let it get inside you elsewhere it's safe enough for your mouth.
Exceptions...
He misses... LOL, I'm usually not down for clean up (aka lick up) duty unless it's just on his chest or something.
He askes to put it somewhere else like face, breasts, etc...
"He" is really some total stranger... in which case what are YOU doing down there anyway
Hope I'm not offending any die hard "spitters" but honestly, when you think about it if it's the man you love then why not? It won't kill you.
