How to get online girlfriend to willingly move on to second base?

I’ve been dating this girl online for almost a year now. I wanna hit second base next time I see her, but 1: I don’t know how to bring it up and not make us both feel awkward, and 2: I want her to be 100% aware that her opinion DOES matter, meaning if she doesn’t want to go up a notch yet, or feels it’s too early, I will respect that! Does anybody know any good approaches? She isn’t online that often, she’s really shy, kind, and understanding. I only meet her about once a month, and feel lonely. I’ve told her this, and…I…think I might…well…love her. She tells me her life is horrible (I trust her completely) and I don’t want to make anything seem worse, or make her think I don’t care, am trying to control our relationship, etc. How can I convince my online girlfriend that it’s time for us to move on to second base, without forcing her to agree against her will? I’m okay with trying to convince her that it’s time, as long as it doesn’t involve anything that could pressure her! My girlfriend is HER, she has her own role in the relationship, she is a human being, with a sentient mind and emotions, SHE HAS A CHOICE!!! That is the bottom line for me. If one person in a couple wants to get more serious, but the other doesn’t feel ready, then they can’t afford to get serious. Does anybody have any advice? As long as it doesn’t involve forcing her to agree, I’m willing to listen Thanks!
