27[F4M]California/online- trying to revive my sexual life from zero

As you can tell from the title, I'm having problems with my sexual life and marriage. My husband and I haven't been in good terms for months now, and I haven't had any dick or sexual activity with him or anyone else since. I'd like to start slowly, with some flirting, maybe some sexting and nudes trading, if we like each other enough, and so on, and maybe one day we'll meet and have more than just fwb. Who knows, anything can happen
