That is not a stupid question! Bettlejuice... that type of remark doesnt help anyone.. i know that you know that...
parasites are passed through sex! It is important to either cleanse with your partner oruse protection. Our bodies do have thier own natural protection to parasites.. but in some people who have weakened immune systems..this is something that is a relavent fear... especaially after 1-6 months of cleansing.... you dont want to get more..or be passing them to people..
I would say go on how you feel... your body intuition is right..and you will know when it is o.k..... but if this is a long term partner... you might want to consider getting him/her to do the cleansing as well.....
