aight so there’s gunna be a party tmw and i would like to know what can i expect with alter ego and soe mixed? i am young 19 year old so you know what i want 
and ofcourse i know i have to do my part!
If you are going with that one, I would suggest at 19, you keep the TUTH to the bare minimum - a half or one spray max. You could keep the togo and top-up as the night goes-on and the atmosphere gets less inhibited.
In fact you might find it better to start with just SOE, keep the togo in your pocket and add-in the TUTH as the night goes on - IME, with younger women, any positive response to none gets better as the party hots-up!
