I am kinda considering taking the pledge but it is a big ting to do so can i have some information and the pros and cons? and how do I tell my paretns?????

well i would suggest sit your parents down and talk to them about it. i'm sure they would be happy taht u are sharing this info with them.
as for pros and cons they can go on forever.
pro: u are 100% veilig from STDs, pregnancy.
in a way for your future spouse, u are giving him a gift ( in a way)
cons: exposed to STDs.

there is much meer but too much to lijst them all. i would suggest getting a confidante so u could talk to them.
i would also suggest checking out thsi workshop called no apologies which could give u a better idea.
