She contacted me and asked me a bit about myself and relationships. She ended the conversation so I asked what it was all about. She said she thought of having sex with me yet that I don't seem interested.

We concluded I'm monogamous though I said I prefer not to define this (this was before she ended the conversation). So when she said that a part of me got horny and got kinda stuck from there.

I am left internally shrugging. I've never interacted sexually before. It's a shock, and a part of me wants to go for it.
I could all of a sudden jump and say how about we go for it in some sort of way.
It's a sharp jump for me, as I've mostly been concerned about emotional/spiritual love. I may be able to get sex, but the emotional relationship idea has always been a deep part of my heart. Yet now with the sex offer it feels like something I should go for instead of neglect.

Really odd to me. One thing I can tell (which I've already told) is I've never got the chance to interact sexually nor passionately. Never even had a first kiss.
