On December 23rd, i got sick with the flu. i had it for 2 weeks and now i'm just battling coughing. I'm on antibiotics and cough syrup and for this past week i haven't had sex, but thursday me and my fiance did and i could not orgasm. I wanted sex, just couldnt' orgasm. We did it for like 30 minutes and i couldn't go on. We tried again later on, still no orgasm. Friday, did it two times with no orgasm. and Saturday, again, 2 times, no orgasm. I'm scared, could my robitussin be lowering my sex drive? i usually have a very high one. Could my past illness contribute to me having less testosterone or something? help
