Bikini line horror, razor bumps plz help


Does anybody get bad razor bumps on their bikini area? I have suffered from this ever since my first time shaving at 12, I have tried everything and nothing works, I’ve been using Tendskin and it works great but I’ve been using it so long that it’s not really working like before. I dread summer time because of it, I have many bathing suits and don’t feel comfortable wearing them. I’m going on a cruise in July and I’m petrified to wear a bathing suit.
