i had sex with cow 8to 10 times without condom,is there any possibility of HIV infection



A cow??? Dude, really, how desperate are you for a date? So you had bareback sex with Mr. (or Ms.) MOO and you're wondering about the possibility of HIV infection? Well, OK, I can advise you that the cow is at absolutely no risk for contracting HIV. (Neither are you, but you could contract other diseases from your barnyard romance. So knock it off before you get turned into the SPCA - Society for the Prevention of Cruelty to Animals).
