I do believe you can contract hiv through giving oral I've had and still have some very weird symptoms going on that I've never had before random brushing,groin pain,painful scalp,sore throat that comes and goes,low grade fevers that come and go,cold sore on lip white spots on tonsils, red bumps on throat,headaches,chills,color changes on my skin ,possible weight loss,body aches,weird brown spots underneath skin and more I also brushed my teeth before this and had bleeding gums ..
