i've actually experienced in that subject, and i can only tell you that on the one hand, if you do fuck her, you WILL gain experience and be more confortable the next time you have the chance to be with a girl.
on the other hand fucking someone you don't feel attraction for fucks up your self-esteem. you do feel cheap and lame afterwards at least in my experience, i lost my virginity to a 31 year old colombian tourist in the stairs of the apartment of her friends place where she was staying, and although its a hilarious anecdote i did fill like shit the day after.
it does go away and you do take the fucking heavy ass burden of being a virgin off your back, though.
i only know if i had to choose again between loosing my virginity to her or staying a virgin being that i was 18 or 19 at the time, and that was already fucking up my self-esteem, i would definitely fuck her again. it does take the glair out of the sexual experience all together, and you learn that sex is not such a big deal really.
probably every girl in the world would disagree with this advice, but for me at least my virginity was a burden and once i got rid of it, i did feel more confortable, so i advice you loose it to whoever you can, the more you like her the better of course, and from there start targeting hotter and hotter girls, cuz virginity in a man is just not attractive to most woman. not because its unattractive itself, but because of what it says about you.
also it fucks you up in two ways cuz not only its unattractive and it says you are not quite mature yet, it also makes you more nervous than you would be around the idea of sex with your target girl often, and given that you haven't experienced, you may think its a bigger deal than it is, fucking yourself up
hope this helps! im sorry if its unpleasant to be told this, i sure know i felt like a dick while writing some of this, but this was my experience and maybe it will be of use to you taking your dessition

good luck, and if you need any more help just pm me
