Theoretically HIV can be transmitted by kissing, practically not realy since there would be a lot of bleeding involved that would turn it more into some cannibalistic fetish thingy than normal kissing. HIV is tipically not transmitted via saliva, which would be the primarily involved bodily fluid in kissing.
So basically kissing is considered a very low risk.
Mutual Masturbation is about the same. A healthy individual without open spots on his body will not become hiv positive since HIV is not transmitted via the skin. Also pre-cum contains a low concentration of HIV if the person is virulent.
You would have to elaborate on the urethra-part, how would you do that?
I would say you would have to be pretty talented to catch HIV with that.Ever since that happened I only kissed and I had 1 mutual masturbation with another guy.
What do you think?
Educate yourself about HIV. There are official sites, health sections on gay webpages and so on. After that you will know how to be safe and when to be cautious and you can have a fulfilling sexlife without unrational fears.
