what do you guys think about the both of them being used together with no other mones? what kind of reaction would I get from my 20 year old girlfriend?
They should work well together. Because of your ages I’d go with 1 spray TUTH and 5-6 IShine (if you have 1x IShine). Should produce a happy mood with sexual undertone.
A sexual undertone will be great for the early night life. If I want more than just a sexual undertone for the late night when we’re alone should I spray one more TUTH? I’ve heard it has negetive effects on women if too much is used and I don’t want that to happen.
The best answer I can give you is try it out and report back, if you make it out alive 
See how she reacts to 1 spray before using 2. Some people can’t even use a full spray, they use half sprays. Like Steve said, eventually you’re going to have to try it if you wanna find out for sure.
that’s true. I just wanted to get a jist for what I should do as to not destroy the mood. I hope TUTH works like everyone says!
