I have an issueeee. Help?

Okay so on a more personal note, this goes out to all the Ladies. ! So about bikini lines.... if waxing is the last thing I need to spend money on, & when money has been wasted on products that sound promising but don't work, & when a razor just doesn't seem to do the trick leaving scars & unattractice marks on my body, what's a girl to do? Is waxing really my only hope? I see nothing but pain in this option. And also, the hair is not long enough as I have previously attempted shaving.... Do the products work and I haven't been using them properly? Have I been shaving incorrectly? They say shave in the direction of hair growth however, it doesn't all come off doing so. Is this a medical issue I need to see a doctor about? I complain constantly about it to my mother and she says, Well take care of it! But I have no idea how otherwise obviously it would be done! Anyways, I feel as if I am the only one as friends and family seem to have it taken care of. Also, my legs.... when I shave my legs they stay shaven for less than a day! and I honestly don't understand because I don't shave often at all. Please help!
