Blowjob

If the guy you are giving a blowjob to is healthy and disease free, then there is no reason for you not to swollow.

There used to be a myth that cum was fattening but in fact it contains an average of about 15 calories - so I would not worry about that.  There are some that say that as it is full of protein, it is even healthy for you - a bit like the white of an egg!

Here is an interesting website on the subject but despite what it says, do not feel obliged to swallow when you are giving a blowjob, it is your decision.

Enjoy!

unless he got some STDs then no, it's not dangerous or bad in any way.

it's a fact that swallowing sperm is harmless

if everyone is healthy then no, its not bad for you at all. in this case it can do no harm to you whatsoever. Be warned tho, its also not helpful in any way: wont clear skin, whiten teeth or anything like that. any guy who says otherwise is wrong . However, many std's and such are highly spreadable in this way so i reccomend that wveryone b tested. Otherwise b safe n have fun!

'swoling his cum'? do you mean SWALLOWING?

first of all...it is not "full of protein" like an egg white. i would love to see where anyone has been able t find the nutrition breakdown of a mouthfull of sperm...please share your findings.

as stated above...STD.s can be caught during oral sex. everyone who is having sex needs to be tested. 

catching a sexually transmitted disease doesn.t sound "harmless" to me sjbang. where did you find your information that "it is a fact..."? again, do share. 

it's fine to swallow his sperm. it may actually be good for u, as sperm contains protein.
