The good news is that this is completely normal! The bad news is that this is completely normal and unfortunately we have hair everywhere!
Don't worry about it seeming thick - hair is naturally different around the pubic area.
There is not really much you can do apart from continuing to shave or looking into other hair removal products - if you do make sure you read up on the product and follow instructions as it's not an area you want to irritate!
Just know this is normal and a burden for us all and the be smart with hair removal (if you want to do this - no real pressure) so you don't accidentally harm yourself.
