Hey Alissa!
Welcome to the forum sweetie! It’s nice to have more ladies here! 
OMG, I love yoga, it’s awesome!
What effects or reactions are you looking for? if you tell us, we might suggest you products that you might be addicted to lol
Meanwhile, do check out instant sexiness, I think that every lady inthe forum got to have 1 of these in her dressing table lol! This thread might help you make a decision on is/a or is/b A break down of IS/A and IS/B but I love them both lol
Have fun!
