i guess u heard this question a billian times ,it is a classic question so please bear with me .
oral sex transmite disease if she has an injury in her mouth ,an infection or whatever ok i do understand that but what is the pourcentage of that happening and capturing it ? is it must do thing to wear a condom in oral sex ? cause i used a condom last time for the first time in oral sex and i didn't feel nothing you loose the whole point of it with the condom . am i putting myself in big danger if i didn't use a condom only in oral ? is doing oral sex without condom is as danger as sex without condom ?
thanks alot for your support .
