Hey there,
I was in a very similar situation to your girl friend so I can totally relate to that and pretty much everything you said. Its hard to explain exactly how I feel about sex, but I'd definitely say I had an incredibly low (nearly non-existant) sex drive just like your gf so I can totally relate there. And I think you may be right about the insecurity thing and that may very well be true. Many girls especially older virgins I can imagine would be pretty scared of sex and the whole concept of sex.
However, I can understand your view too, sex is an uncontrollable desire and you can't help but feel the way you do. My ex bf was also very sexual like you and he waited a few months for me, but he couldn't handle the pressure and I'm guessing that was one of the main reasons he broke up with me. I don't blame him at all if that was why. I'm surprised he lasted as long as he did really. So I sympathise with your situation.
Anyway from my experience if sex really is that important to you and you really feel like you can't live without it then you really have a serious issue here. It is possible that you're gf will never change her views on sex. I'm pretty sure I wont. I've done much thinking about it, and I've come to the conclusion that I am probably at least some what asexual (meaning I have little to no interest in sex).
Unfortunately there is very little awareness of this in the wider community and a lot of people would say I'm crazy (maybe I am
, but that’s a unconnected condition) and that asexuality doesn't exist. But it does. And obviously sexuallity and how sexual you are is a spectrum so some people are very sexual and some are barely sexual at tall or non sexual.
Anyway going by my own experience my advice would be to really talk to her about the whole thing, give her a bit of time maybe. But if it persists for much longer, you may have to consider the possibility that she’s verging on asexual and just has little to no interest in sex.
In the end you either have a sex drive (as you clearly do + most people do) or you don't. It’s not something you can really force or pretend (well you can to some extent, obviously you can make yourself have sex / allow someone to have sex with you, but if you do you probably won't really enjoy it).
For some people sex just doesn't feel right. Just like homosexual people don't want / enjoy straight sex, or straight people wouldn't want / enjoy homosexual sex... its along the same lines really. Some people are just non-sexual and they don't want / enjoy any sex. Since she hasn't experienced sex, maybe she'd feel differently after experiencing it, but not necessarily. And if she really feels no desires that way and is that scared/ against sex then its possible that she’s just not a sexual person.
Sex is different to romantic love though. Think this is what my ex bf also couldn’t understand. You can still love someone and feel strongly for them but be asexual. It’s a tough situation, and at only 18 she may just be scared of sex. Maybe she just has to really think some things through like I did. If its just a low sex drive she suffers from maybe she could get pills to help her with that from the doctor? Its sometimes possible. And if she’s taking the contraceptive pill already this may be significantly lowering her libido.
I’m sorry you're in this situation, I’ve been there so I know how hard it can be, well from her side, scared that you’re going to loose the other person, so I guess you feel something similar if you fear you may break up over this.
Anyway talk to her,
Hope it works out for you, I really do.
PS- In the mean time maybe try looking at this message board. It really helped me. Maybe it would help your gf too - [url]http://www.asexuality.org/discussion/[/url]. For a long time I thought there was something wrong with me that I was alone, that no one else felt as I do. But its important to tell her there’s nothing wrong with her, whatever happens and she’s not alone.
