well, oral sex is (99%) safe, provided you do not have open wounds (herpes, or from shaving) on your dick and the girl does not have open wounds (brushing teeth too hard, oral surgery) because the acidity in stomach acids (and therefore in the saliva) are not conducive to transmission. HIV loves blood and semen. (the same applies vice-versa to cunnilingus)
I dont know about lemons killing hiv, but a healthy dose of lime up the coochie will let you know if a girl has open sores in her twat.
If she howls - dont eat.
If she purrs, play with the kitty.
If you fuck, wear a rubber.
