Yeast infection or herpes

so i recently had sex with a new partner. used a condom at first but i am allergic to most lubricants and latex :frowning: he ended up taking it off and i was fine (happened last saturday). but wednesday (4 days later), i got an itchy sensation. no burning or pain, but it reminded me of the time i got a yeast infection. it doesnt really look the same though. could this be herpes!!
