hi dear although chance of contacting bacterial std
is less as it requires bit trauma to the penis. but what u should be worried of is hiv
and hepatitis b
. both are deadly and both spread through even slightest contact of blood. now there are two things u can do. either u meet a doctor and take post exposure prophylaxis or if u have faith on ur partner and u think she might be hiv negative, u can wait for a week and get p 24 for hiv done.
