I'm new and I need suggestions/advice

Hello, I orded the Instant sexiness B and the instant openess, it’ll be here today. I have a date on Saturday and would like to try them out for the first time. My quesion is, how much do I use? How long does the effect last? Since this will be my first time using the mones, I don’t want to go overboard or make things too uncomfortable. Thanks for your help ladies.
Oh, my personality is that I’m usually reserved around new people, I’m much more talkative when I know someone. Thanks.
