No.
It's less risky than sharing a needle with someone HIV positive, but it's not "safe".
If you swallow your own semen, then no, you can't get anything new. It's quite safe. It's fairly safe, too, to swallow someone else's semen.
no
Yes
Of course it is. People swallow it all the time -.-
I think it is :)
No. As long as the male has no STD's it is perfectly safe to swallow.AnswerSwallowing semen during oral sex is harmless as long as neither partner is carrying any sexually transmitted disease.
Yes. The amounts that might possibly be found in his semen are at such trace concentrations it won't do a thing.
It's probably not safe to swallow H+ sperm whether you're pregnant or not. I am not a clinical doctor, but this is a question you should ask him or her for a definitive answer to. (And trust me, you won't be the first person to tell her doctor that she swallows semen...)
Infectious diseases can be transmitted for semen so swallowing semen is not consistent with "safe sex". Other than that there is nothing particularly good or bad about it.
No
The rifampin in the semen will not cause any problems, but their semen may not be safe to ingest. Rifampin is an antibiotic given for many reasons, including STD's. If the rifampin is being given for an STD then it would not be safe to ingest the semen, not because it has the rifampin in it, but because it may still have infectious particles in it.
Yes it is safe. I do not advise doing that though. It is safe and you can do so if you wish. You cannot give yourself any infection from taking your own semen. Many males masturbate and swallow their own semen. Recent studies have found that consuming human semen reduces depression. You can find an article about that in the related links below.
