Hello Andrew Welcome to Pherotalk
Gay men react well to socials products and small amounts of masculine products. They are attract to men so the natural pheromones a male makes and uses to attract women would be the same thing you would use to attract them.
Trick is not to overdo it because you really do not want to come on to strong or overly aggressive.
Instant Honesty would be a great choice, This is a deep conversation mix but it also brings a feeling of comfort and connection.
Instant Shine works well with all people gay or straight.
Mystery boyis good, it has a lot of socials with just a touch of masculine pheromones and is perfect for the gay lifestyle. MBis said to be… TAA, TAH, high amounts of Alpha Androstenol and a dash of Androstenone. I left one out for trade secret purposes. 
It comes in the AMMO scent which is delicious. Simular to Hugo Boss.
Instant Openness is fun and chatty and also causes comfort.
There are some test mixes to try and some putatives good for your lifestyle as well. Keep in mind these are advanced products and are non returnable. You may be interested in them later so I am going to mention a few so you can do a search on them in the forum and read up when you have time.
TAL primarily used by the women but men have been testing it and there have been reports of increased interest from men.
TAH worth trying and its one of the ingredients in Mystery boy
P74 evokes more bonding with men, Sort of has a adoring effect.
MX203 High in nols and P93 with just a low amount of Androstenone which is why it may be a good choice.
The AMMO scent which is what MB comes in may be tuff to use with your own scents but it does work with some scents. The reat will go great with your cologne choice. Most products come in neroli which blends with anything.
