You mentioned that you've never handled contact lenses before and I would strongly advise that you make an appointment with an optometrist to get a prescription for your base curve and diameter (and power if you need vision correction). You need a prescription to legally buy lenses in the US (even if you don't need vision correction) and more importantly you need properly fitted lenses made from compatible materials to safely and comfortably wear contact lenses.
Even more importantly, the optometrist will show you how to insert, remove, and clean/care for your lenses which gives you hands-on practice and someone who can answer all your questions and give you specific answers for your needs (all during your appointment). If you bring a trial certificate to your appointment you will receive a pair of lenses to practice with.
We've been compiling a thread of info that's a sticky in the Makeup forum, Contact Lens FAQs
. You may wish to give it a read as there is plenty of info for people new to contact lenses including care, insertion, and removal of lenses. Please note that reading the thread is not a replacement for seeking professional consultation with an optometrist.
Once you start practicing, it is quite easy to insert and remove your lenses. It only takes me matter of seconds and I've been wearing lenses on and off for 15 years. Please consider going to the optometrist because you'll get valuable personalized information concerning yourself and contact lenses that the internet cannot offer you.
