boosh welcome to the forums ! 
Glad you stumbled upon this wonderful community and i know you will indeed find it very rewarding. Always good to have a scientific mind at work here and it should def help in your testing and reporting which would be awesome if you share your experiences on here in the mens section and/or a journal.
If you are shy and deal with approach anxiety id suggest you look at IO or CTTM2. IO will relax you and those around you , and will make conversations seem to flow nice and easy without that awkward silence. CTTM2 will help others around you as some users report it being able to have people approach them and make the contact initially which is usually not the norm for them.
I also recommend instant shine for you if you want to be more happy, confident and smiley. This should make you seem more approachable if you are in high spirits and smiley. And as far as an attractant for the ladies that product is going to be ammo, all of which i suggest you get in regular strength at your age and first starting out. its more versatile this way as you find your sweet spot in sprays with them.
You can cover the instant line fragrances after they dry down about 10-15 minutes in and then your favorite cologne will preside over their scent and you will no longer smell the light neroli smell it comes with. Ammo is more tricky cuz it is scented at cologne strength, therefore you would need a cologne that was very similar or it may clash and be scent overload !
A314 could be good in your situation and age if you want respect, confidence and the alpha aura. It is more of a slow burn mone and is in oil based and the hits are generally less subtle but build over time.
A lot of the effects , self effects are instantaneous after application if you get self effects like most individuals do. Mastering the art of application is all about finding your sweet spot and thus i will provide you with a link here to read
