Welcome to the forum.
As you suggest yourwelf, you are indeed much more worried than you should be. As with the other exposures you have asked about on the HIV prevention forum (both domestic and international) and the community forums, you continue to be concerned about very low risk exposures that carry little or no risk for HIV. You describe a partner who is very unlikely to have an STD plus exposure events (oral sex, superficial exposure to menstrual blood) that carry no risk for STD transmission. You are at no risk of any STD from these events. You don't need testing and shouldn't worry at all about it.
I hope this has helped. Best wishes-- HHH, MD
Thank you for reply and yes indeed this made me feel better.
I just want to know about hepatitis because when I searched in the net it is written that HBV can transmit even there is no sexual contact. This dry blood on my boxer may touch my urethra. This is what I was worried about. Coz I do not like contact with somebody else blood whatsover there is.
Yes, hep B can be spread nonsexually -- in fact, blood contact accounts for more infections that sex does. But superficial contact with small amounts of blood like you describe is entirely risk free. You should not be at all worried about it.
