Ahahaha XD the title really made me laugh, maxwell. No offense XD
Nope, deo won't be the solution. It just adds to some charm (who wants to stick around someone that smells...unpleasant, or even consider hugging them and such? Unless their nose has a defect, but that's quite rare, unless traumatically induced XD).
It's about how a guy takes care of himself. Personal hygiene. Deo would be useless if the guy doesn't get a decent bath everyday (and i mean not just standing in front of hot water.
Like really soaping and scrubbing every part, specially the crevices where sweat and dead skin accumulate: armpits, neck, groin, flexure areas, and such) If not cleaned properly, bacteria and even fungus could grow there, causing the unpleasant odor. No amount of deo could rectify that. A clean skin looks and feels and smells great, even without deo

.
Next,
build that body. You don't have to be brawny and all muscular, just physically fit. Get to walking and exercising daily. It builds your confidence as you see your body improving, and quite a social exercise too. It brings you outdoors, and you could meet a lot of people as you go along.
Finally, a solid and intimate relationship with GOD. Fill your everyday with
prayer and meditation of HIS Word. Feel secure in HIS love and HIS awesome plans for you. If you know you are so dearly loved by GOD, and that you're on your way to becoming the best that you can be 'coz HE is working on you daily, you've just found the ultimate source of confidence and peace you could ever have

plus HIS light shining through you as you are filled with HIS joy and presence will surely catch the eye of many ladies, specially the woman HE has made for you

see for yourself! But believe me, the ultimate reward is simply getting deeper with the LORD. Everything else is just a bonus

I've discovered this just recently, and i am blown away by Papa GOD's love. I hope you find what i have found in HIM.
God bless you with a deeper growing relationship with HIM!!!

may HE grant you the very desires of your heart!!
