first let me say i am so very sorry for the horrible experiences you had as a child. your dad hopefully is dead or locked up. as far as swallowing semen i don't think it's harmful generally so long as the man has no diseases. it is mostly your mental attitude toward swallowing some find it revolting. you cannot get pregnant from this.
my husband wants me to have oral sex will i get sick if he comes in my mouth. i was physically and sexually abused as a child. my husband knows about this. he has asked if i would preform oral sex for him will i get sick if he comes in my mouth? are there germs that can also make me sick. when i was forced to do this as a child and my dad crammed his dick in my mouth and came i threw up and began to chock. i was also afraid that i would get pg.
