Not at all
Just swim. Don't touch it and it should stay on. Mine stayed on with no problems. Swimming and bathing is okay, per the company's website. But if it falls off, put on a new one.
Yes, no reason not to.
Better late than never. Go for it.
Yes it is, but washing it may lengthen the life of the suit.
yes it is okay to have it once in a while
Whether it is "okay" or not is an opinion. As long as the pyjamas cover enough of your body to where you're not in violation of any indecent exposure statutes, then you are legally able to wear pyjamas in public. That being said, private businesses are not obligated to tolerate it, and they may remove you from their property or refuse to serve you.
yes it is okay to have your hair tied up while having nits
Swimming after getting your piercing is not a good idea. The water has a lot of bacteria in it which could cause an infection. It is recommended that you wait the full heal time before swimming, which is 6-12 months.
Yes it should be okay. However, you should always listen to the lifeguard.
Not while your seeing him/her!!!
Yes, you can do anything you like on your period. It's perfectly okay to play sports while menstruating and if using menstrual pads - with the exception of swimming and water sports. Active women do often prefer internal menstrual products like tampons, menstrual sponges, menstrual cups, or softcups, but it's perfectly okay for you to exercise with external menstrual products like menstrual pads. As long as you're comfortable it's fine.
