Re: What to do?
I dont know what to REALLY say about this. But if you dont like "cum" on you, or in you, (the mouth that is), then why give him a blow job in the first place? Unless you two do oral sex in the shower, then when he ejaculates on you it gets washed off.
But if you're that intent on blowjobs, then you gotta face your fears and let him, or think of ways of keeping yourself clean while at the same time doing oral sex all the way...I dont know any ways to tell you of since it probably will happen, (he ejaculates on you). But if he does respect you, then he will point it in some other direction at the last minute...
If you choose to run away,
You live to run away again...
