[M] planning to buy new undies and browsing through the collection made me horny

i am planning to get new black undies for myself
possibly hipsters and i was scrolling through the website
little did i know it would turn me on to such an extent
i am straight and i cant stop imagining my girlfriend pulling my pants down and seeing the well fit underwear on me

i am well built so it gives real confidence just imagining myself in those undies and feeling confident near women
