So, lets begin:
(first excuse my spelling because english is not my native language)
I’m 36, male, a bit introverted and shy around girls.
If the girl I’m with is in funny, talkative mood - so am I, but if she is sitting quietly and not talking so am I and I can’t do anything about it.
I work in environment where I can meet younger sporty girls, but I don’t have the guts to escalate things beyond friendship.
I have come here to try some new approach.
Any ideas and suggestions are welcomed…
Weeelll, welcome to the forum 
Congratulations on taking the first step towards expanded knowledge.
To answer your question, there are a variety of options for your situation. You seem to be the type to take your cues from whomever you are with at the time. The beauty of pheromones is that most every molecule affects both parties - both you and the sporty girls.
A few starting points would be IO, IG and Ammo.
IO - This one will help jump-start conversations, both on your end and on theirs.
IG and Ammo - will give you an appeal that will keep them interested past the initial conversation. Specifically IG will project that charming protective image, and ammo will add a somewhat sexy, somewhat alluring image.
Thanx for your quick reply redlion.
I’m not sure about IG, I don’t think that looking older and wiser would work, I would go with something opposite.
One thing I always remember on first or blind dates is that it’s just as much their job to entertain you as the other way around.
For a date I find that ammo and IS is a GREAT mix. Ammo is a sexual mix and great at attracting, but it isn’t OVERLY sexual like TUTH might be, so its great to where almost anywhere. IS is great as it gives off a youthful fun playful vibe that will make you and others feel awesome and generally social.
Let us know how things go!
Welcome to pherotalk 7,
Lol, well if you can’t enjoy a good silence with someone then you are not completely comfortable with them.
I think products like Ammo, IO are great starters for what you described.
Your gc was issued!
After a lot of reading and browsing the forum I have made a decision:
I am going with ammo and ishine.
I think you’ll be pretty happy with this choice
Make sure to write reports on your findings.
Oh I don’t know about that. OK, my experience is purely anecdotal but I have been around sporty types a lot over the years and two of my main exes were active sportswomen themselves - One was regularly competitive at national level in her heyday. Nine years and seven years younger than me respectively.
Anyway, I have noticed that sporty women do seem to have a bit of a thing for slightly older or more mature guys and as such can often respond to more overt none and high status signatures - Think on how many of them do hook-up with their trainers, senior athletes in their own sport and the like.
However, they also seem to like to party - HARD! so the socials and high status but socially engaging properties of IG might be quite useful to you.
