I Need Help! How Do You Take That Next Step To Feel Comfortable To Seriously Date Online?

I need help! I’m a 26 yr old guy starting to delve into online dating as another venue. Up to this point, I’ve always felt meeting online and conversing intimately online to be two dimensional for my taste and just not for me. I’ve always felt conversing and relationships in person were more genuine.
But, I’m trying to change this because I met two great girls who would like to know me and vice versa online (unfortunately it’s long distance too). This experience is completely new to me and I need basic tips on communication, feeling comfortable doing so and being able to keep things fresh and non repetitive. I think my main problem is just getting past the ‘how are you’ type letters and feel i need to up the intimacy to show interest. If I don’t I usually withdraw but how do i do it without seeming like a pervert or coming off desperate?
I know I’m asking a lot, but could you provide me with good and bad experiences, several things to avoid talking about and things to talk about?
Much Thanks!!

Online Dating.. Next Step?

Okay, I’m really hoping someone has some experience with this.
I am dating my boyfriend online as he lives in a seperate country. (please don’t give me the “LDRs don’t work” comment, thanks)
We have been ‘together’ about 2 months so far but have been talking for longer. He lost his virginity when he was 14ish and I haven’t lost mine yet. (we are both almost 17). If we can’t see each other for about a year, the time is bound to come up (my guess is soon) where he will want to ‘do it online’ if you get what I mean. I am happy to talk about it all with him, its just that because I don’t have much experience, I’m not completely sure with how to say it, you know, how to put it in words for him.
I trust him completely, he knows that I am still a virgin and he respects all of that.
Looking for advice or tips from anyone who’s been through this before? Thanks
