Dude! You go as far as you can as fast as you can. Just because she's a virgin doesn't mean to say she isn't wanting to do it right now while it feels right for her. Sex is supposed to just happen, an its your job to make it happen. Each girl will be different. Some will only let you kiss and you can't push any further. They then might get ASD about it and keep away, basically its a failed escalation and if she slut shames herself for doing that with someone who isn't her boyfriend its fucked. That is out of your control....
The other side to this, this may be the furthest they have ever gone and therefor invested in you. If they like you enough they will see you again. One virgin might let give you a hand job/blow job and let you finger her and give her oral. Others won't. Each situation is different and not just for virgins. Some girls will not fuck you on the first date. This is when you would use the 2 date method.
The issue as we know with second dates is that they don't always come around. Whether the girl is a virgin or really experienced you might not ever get another shot at it. The exchange remains the same. Keep your eyes on the prize, push for the goal, do not rush.
See how the girl responds and what you can do.
There is the whole mentality of don't kiss until your fucking them, which is great because it keeps your sexual tension, doesn't give it away and its a reward when you get what you want.
@Tony D has advocated kissing before and letting his value do the rest. Personally I have had more luck kissing the girl first than waiting until am fucking her.
Like you I have missed out on my fair share of virgins, one of which I really liked. I am kicking myself to this day that I didn't just fuck her that night while I was with her. At the time I couldn't make the logistics work in my head (I didn't want her first time to be in my car, miles away when we were leaving with our friends in different directions. I figured I would get to much LMR trying to vacate the club and trying to do it, figured she was invested enough and I will see her again and she cancelled the date) and I expected a lot of LMR from her, this wouldn't have been smooth so I opted to be non pushy, cool and relaxed and set up a date to convince her that I did actually like her. Clearly this didn't work for me this time.
