My guess is no, since it requires blood to blood contact. I would also imagine even if you swallowed blood, that stomach acids would destroy the virus. Not positive though about that. You may want to get yourself checked though for other possible risks factors such as sharing razors, toothbrushes etc.
From a review/opinion article:
Assisted procreation in cases of hepatitis B, hepatitis C or human
immunodeficiency virus infection of the male partner
Honeck et al, Human Reproduction Vol.21, No.5 pp. 1117–1121, 2006
The risk for sexual transmission is higher for women than men, but in comparison with other viral infections, the risk is low. For HCV-discordant, monogamous couples,
the rate for seroconversion after 10 years is only 2.5% (Neumayr et al., 1999; Zylberberg et al., 1999). The risk of late sequelae though makes the use of condoms to protect the
healthy partner feasible (Valdivia et al., 2003)
In English, the pertinent parts of the article:
Virus is present in low amounts in semen
The rate of sexual transmission seems to be very low
Use condoms anyway.
If you wanna get pregnant, see the obgyn first for sperm wash.
If he is on treatment, ribavirin is also found in the semen. RIBAVIRIN can give your baby birth defects - probably better to hold off on swallowing if so.
Alcohol mouthwash like listerine after exposure may give some protection.
Getting semen in the mouth can potentially be dangerous: the gums often have small cuts especially after vigourous toothbrushing.
In short: probably better off NOT getting semen in mouth or swallowing.
He is a lucky man to have a woman devoted enough to ask. Enjoy, both of you!
