Do I give off a vibe or something?

I don't get it.
Is it me?
Is it men in general?
Is it society?
What the fuck is it?
Why can't I have a conversation with a guy without them always trying to talk about sex in one form or another.
Its really damn annoying.
Whether it be asking how long it has been since I last had sex, what position I like, if I would sleep with them, if I watch porn, if I knew that people thought about sex in one form or another every 10 seconds of the day, telling me about sex with random people that they had, etc. it gets brought up in every conversation.
No matter how many times I say I don't want to talk about it. THERE IS OTHER SHIT TO TALK ABOUT!
And then I get told I am the weird one because "It's normal to talk about it." I know it is, its a human thing. A natural thing. A normal thing. A beautiful thing.
Not for me. Not in my experience. Which I give the short version of why, but they apparently don't pick up on, when I tell them to stop bringing it up.
The topic keeps getting brought up no matter how many times I ask for the respect for it to not be brought up, until I finally get short with them, then they need to "respect my sensitivity to the conversation topics" and the attitude with how they talk to me changes. It goes from talking to me like any other person to all of the sudden I am some delicate little flower and they need to walk on eggshells around me.
I am an intelligent woman. I am an interesting woman. I can bring a lot to a conversation that has nothing to do with the naked human body. If you want to talk about something I don't know much about, but I find interesting, then I want you to tell me more about it, and I will most likely look stuff up when I get home.
I can sew, can't read a sewing pattern to save my life, but I can sew!
I like building prefab furniture you buy from the store. Especially from IKEA, I see that shit as a challenge. Especially since it's never in English and there is always missing and spare parts.
I like to garden. I might kill everything I plant, but that doesn't mean I don't enjoy trying to keep the plants alive.
There is way more to me that that one stupid topic that always gets brought up, and I really wish guys would just take the damn time to figure that out.
