Single again but it's college so...

Hey there and welcome!

Homme, sounds like Chanel, but quickly Googling the name it could be Yves Saint Laurent.
I do know the feeling of an over-used perfume/cologne! I really enjoyed Aqua di Gio, but then everyone was using it. Not suitable for my “I want to be an invidual!” persona.

So, 21 years young. Really, enjoy your time being young! (OK, I’m just 25, but anyway.) You didn’t say how tall you are or what kind of built you sport.
Considering your age don’t go high on -none, the manly pheromone. Well, unless you really want to go for some cougar love.
Considering your college time I would try some Instant Openness and Instant Honesty. Well, IH is so far the one I enjoy the most, so that’s why I suggest it.
Extraballislit suggested IG, that’s a good pick as well.
And AMMO of course.

Considering my suggestion about Instant Openness, some people say that it can create a easy “come talk to me” vibe together with IH. But be careful, I know young girls can be too chatty anyway! I for myself enjoy a much greater deal of lower pitched, easy talking voice than the “omg omg” screams etc.
I bet there’s still some of that going on, even though you’re 21.

I understood your post clearly, I don’t know if my post makes any sense to you.
Anyway, there have been some links posted already, have a read!

Application points 101 is one of my favorite “FAQs.” Maybe you read it already!

Anyhow, please enjoy your stay, have fun with the pheromones and enjoy your youth in college! Go crazy!
