Hi, for my future education...If I am having manual sex with my male friend (he is fully clothed with shorts but no underwear, and he fingers my vagina), is there a need for him to wear a condom to prevent pregnancy? Since he is wearing his shorts, the shorts already acts as a fabric barrier right? I mean sometimes he touches his shorts or scratch himself through his shorts although unintentionally, but the shorts are a barrier so I guess nothing could get through? Is wearing a condom necessary then?
