<human>: Could you distill the essence of the text into 1-3 sentences?

I have only recently been intimate with my now girlfriend but we've been friends with each other a long time. We haven't had sex fully yet because the novelty of being friends who got together hasn't quite worn off yet. Girlfriend is really wanting to have sex, I do too but I'm pretty damn scared if I'm honest.

I've done loads of stuff to her, I won't go into loads of detail but let's just say I know what she tastes like. I haven't let her do anything to me yet because I'm terrified of what will happen, even though I know it will be fine. 

My girlfriend feels guilty that it has been all her and nothing for me, so she is getting more touchy feely with me every time I see her. I really like her but also don't want to go too far too soon because then I feel like the relationship will die out. We already know each other really well so we have kinda already done that part of a relationship. 

I do like the idea of her touching me but when it comes to it I can't actually bring myself to let her. I feel like she wants to go further than I'm willing, i.e actual penetrative sex.

We are both each other's first "proper" girlfriend/boyfriend, people tended not to go for either of us because they thought we were together since we are so close.

Just thought I'd mention at the end that there is a 9 month gap in age, I don't know if it really means anything but she is a little older than me and I know she has been wanting a relationship for a long time.
<bot>: I much prefer pleasuring my girlfriend and she feels bad for this but I don't like her doing things to me right now.
