First, what is your gf 's situation? If her hiv is negative, you will be OK! Second, the speed from a female to male is very real, but it's not 100%. Because you have unprecedented sex, it still a low risk. The cut is not a consern, you should take care your behavior!
She is clean! HIV negative. I just wanted to make sure, thanks so much for your feedback. I am only eighteen, and those hormones are at their peak. But will do on taking care. Once again, thanks!
