DO IT!!!
It's free with or without insurance I Mexico as well! Just ask your nearest health center and they'll give you more info (IMSS, Condesa, there's a looooot of options!!)
Its 2024, if you're sexually active and dont use condoms I HIGHLY SUGGEST you get on PreP/Descovy/Generic versions. ITS ESSENTIALLY FREE THROUGH INSURANCE.
Ive been on it since 2018, unless you cant take it you have no excuse not being on it. Stop putting yourself at risk!
