I'm just wondering what to do as I have a girlfriend that is 6 months older than me and we have been together for a year now. This is her first proper relationship and it is my 2nd.

In my first when I was 14 I had a very sexual relationship with my partner but this time around it is only sometimes sexual. My girlfriend will sometimes be very active and forthcoming to the idea of doing sexual activities and the next time I see her she is totally apprehensive and I respect that but I'm unsure is it just her changing her mind all the time or is it because she isn't as sexually mature?

Would like some feedback on what people think

She is definitely sexually and emotionally mature because she very likely realizes she could easily become a mom due to any sexual activity with you or any other male. Are you financially and emotionally ready to be a father? Do you have a great job, savings in the bank, your own home, enough ready money to cover the large hospital bills and all the baby's needs for the next 18 years?

How old are the two of you and what does a properly sexual relationship mean? Maybe she is apprehensive because she is not sure she is doing the right thing.

You posted this in the teen section, so you're teens. As a teen are you ready to be a father? Not just providing the sperm, but actually paying to raise a child? If you answer yes, be warned that I will post the cost of having a child, so you better be able to back up that you're not only emotionally ready, but financially ready as well. For instance, if you're in the US, the cost just to give birth (if nothing goes wrong) will be around $12,000. Unless you have that, and more, in the bank, keep your pants zipped.

She's not sexually immature, in fact, of the two of you it sounds like you're the one that's immature.

You really want feedback? You aren't going to like it.

Since you posted under Teens I assume you are a teenager. The fact that you claim to have had a sexual relationship at 14 indicates you have no clue what a sexual relationship really is.

Sex is not recreation. It is an intimacy to be shared between two people in a long term committed relationship. You don't sound mature enough to be ready for such a relationship.

I too think you are the immature one as all you think is a proper sexual relationhip, and she is thinking of a healthy relationship with more than just sex.

She is saving you both from bad consequences of a sexual relationship between TEENS! Wise up young guy.
