Can I get std from having unprotected sex even if my partner and I are both virgins? Also I keep getting jock itches. Is there a prevention for it?

Tinea? Yeast? Other? It is not possible to have an STD unless one person or the other has had sex with someone else. "Jock itch" is not a term normally used in women, only men. Have you been diagnosed with tinea (same fungus group as jock itch in men)? Yeast (entirelydifferent)? Neither yeast nor tinea is sexually transmitted. Don't assume any diagnosis based only on symptoms; get professional care.
