Welcome to the forums, Putrahaikalz!
I’m a gay, and I’ve used the male products very successfully. Any of the products for men will attract bi men, gay men, and straight women. These groups of people all have one thing in common - they are sexually aroused in the presence of male pheromones. In terms of usage, you can actually use less if you are attempting to attract bi or gay men because they too are producing pheromones of their own.
I strongly suggest getting the Intro Pack for Men. It has all of the products that Justintime and Conjurator mentioned. I think it may come with A314. If not, get yourself a bottle of that too.
My favorite is A314. I get lots of attention from gay men with it. It can be a bit intimidating to some men, but I don’t mind that. It means I get to choose who I speak to. Overall, it fits my personality.
Instant Gentleman is a bit tricky, at least for me because of my age (48). When I wear it around gay men, I come across as a father figure to them. In other words, it accentuates my age. Even with some men close to my age, if they have any unresolved issues with their father, they want me to be their mentor. Yuck! At your age of 28, however, it might give you an extra aura of maturity and respect. If you enjoy the company of older men, IG would be suitable.
Ammo is also a bit tricky, but overall a great product. I had to work on finding the right dosage. At first I was wearing too much. Once I got the dosage right, I got lots of attention (and phone numbers) from guys. So it’s better than A314 in that respect, but the downside is that it doesn’t leave a lasting impression. I
TUTH is also one you can use with both men and women. (You can read about my experience with it in my journal.) So anything that you might use to attract straight women you can also use to attract bi and gay men.
I also recommend trying out Instant Shine, Instant Openness, and Instant Honesty. These three products you can use in combination with any of the products I mentioned. You can combine them to accentuate different qualities. A314 and IShine is an awesome attractant. Add IH to the mix, and you should be able to approach men and women with relative ease.
So don’t worry about if a product is for men or women. In your case, use the products containing male pheromones, be friendly and charming, and have fun!
And write about your experience in the journal section! We need more bi and gay men sharing about their experiences.
Good luck!
