Penis Size 🙄

Okay , so I have a question (it's kinda funny but somewhat serious) . Let's say you meet the perfect guy ! You two connect , you enjoy each other , he looks out for you , he makes sure you're straight first , he's head over hills for you and potential husband . One thing : his penis size . Like sex isn't great but okay . And what girl just wants okay ? How do you bring it up without hurting his feelings ? How do You bring up penis exercise ? Or is this something that you have to deal with and soon get over ?
