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.

If you want to do it, go for it. But realize that sex can either make or break a relationship... and be cognizant of the fact that sex always has risks (physical issues).

I'm monogamous. A friend wanted a sexual relationship because he's polyamorous. While the idea of sex was interesting for me, I decided I'd prefer an emotional connection over sex. But that's just me...

I got concerned about STD's regarding casual sex.
It feels like an opportunity to jump for that I shouldn't miss. I thought maybe it can help grow me into a more flexible and confident person. It's hard enough for me to take things easy and go with the flow so I thought casual sex could break that barrier yet I'm not sure.
Moreover, at my core I want to actually connect in a relationship, as much as it is hard. A bit like in Disney where the relationship is built gradually, and accepts struggles

Good luck and best wishes with your decision.

You definitely should be concerned about STDs. This could turn out to be the kind of opportunity you'd have preferred to pass on!

She contacted me again with hints which intensively turned me on, but I'm still concerned about STD's. I had nothing to respond, although there was something I wanted to respond which came up in my head very intuitively, but was because of the sexual drive.
A friend of mine with sexual experience told me I have nothing to worry about casual sex and that I just use a condom and I'll be fine.
Moreover, the woman sounds like someone who keeps her dietary and physical health in check, so it sounds safe. Still skeptical.
I eventually want to go for it.

Have the STD talk, wear a condom, have fun if you decide to go for it.

I can't believe I'm saying this.

DO IT!!!!

But carefully guard your emotions....(and your other bits)

A woman contacting a man and asking for sex? This is intriguing because I pretty much never see it happening. In fact I am going to go out on a limb and guess you are definitely younger than 25. And I'm going to guess she's older?
