List of sex dolls for serious sites

I am very young (27 years old). After several years of love, I have been single for 3 years. I chose to try sex doll (even if it is very delicate because it is a doll), because I no longer want to share my life. My social code is too strict for my taste to define and accept. Always very lonely, living a lot in my inner world (diagnosed with autism), and I think it will fill the emotional (and sexual) gap I lack. Basically, I hesitate between several sites, and I especially want to know if the site is a reliable site or is rarely recommended. Thank you for reading. I am also new, so I can only say that I use this forum to inform you! Especially there are some sex dolls list for serious sites, it is best to check here first!
