Don't worry about it - I'm sure it will work fine in the future. As long as you get erections when you need to, this will not affect your desire or sensation!
Look, not all foreskins cover the head when flacid, if worried then get out there and get a G/F start a sex life and see how it goes, do you get morning woods, do you masterbate, then if yes and thing work, then you are OK.
Just remember there is a women out there just for you, shy, waiting and wanting.
Good Luck
