So a little over a month ago I made an attempt to get head from a dude. Thought I could get my dick up for anyone that was willing to put my penis on their mouth. Turns out that is not the case. I had condoms in my pocket ready to slap one on and let him suck me off. But I couldn't get hard turns out im not attracted to dudes. Anyways I didnt want to leave him hanging so I jerked my semi hard penis ,until I was ready to cum and asked if he just wants me to shoot into his mouth. Now onto my question , he didnt contact my penis with his mouth but got close enough that I felt one short breath on it. Is there anyway a Std could have been contracted through his breath? Im dead serious. I havent had any symptoms but im scared to have sex with my girlfriend and havent since because im scared that I contracted a std from dudes breath.
