I also don't want to lead them on by pretending I want a relationship when I just want to have sex

Just avoid the topic completely at first. It's easier if you pick up girls IRL, 'cause then you can dodge the whole "interview" process before getting them to bed. Harder to do that with OLD, where they'll typically ask you what you're looking for and so on, before even seeing you.

After already having given them the D once, it's a different ballpark. You can state it bluntly if she brings it up, and she's still likely to keep fucking you for a while (you're already a notch by then, so what the heck). If she keeps pushing (very likely) you can keep stating it, or you can "DARE", until she eventually breaks (or you cave).

Read the sidebar and the recommended books, e.g. No More Mr. Nice Guy, and The Rational Male.

The opposing terms Alpha and Beta are often used to label different male behaviors and traits. Alpha being behaviour and traits that are arousing to women, and Beta being provider traits and comforting behaviour. Being a straight edge guy has relatively little to do with this. What matters is that you unleash your sexuality and work to become more masculine and more interesting as a man.

When I date, either on OLD or IRL. I am honest, I tell them sure I'd love to get into a LTR. What I don't tell them is 95% of the women out there are not LTR material.

Is that being dishonest? Is it more than pretending to be a good girl?

If they come right out and (have the talk), If their slut defense is so strong for you, then that's a real indicator that she's not into you. Next.

Sexual relations are one of the factors going into whether someone is LTR material or not. Along with behaviour/personality which takes in many cases, a lot of time to really see.

So, sure, I'm looking for a LTR, but I'm not rushing it and will have some fun along with way. Why not, women sure as hell are.

I stopped using phrases such as "get to know you" when I was asking out girls. Step one is to eliminate relationship perceptions before you even try to get them out

Secondly, where and how you meet women is a factor. If you meet women at bars/tinder etc then expect that they want something more casual. If you're meeting girls in more reputable ways they might be more LTR oriented

Also, at 30, you're going to be running into more girls hitting their epiphany phase and trying to settle down, especially if you have a successful stable job such as yourself

If you hook up with a girl, dodge all topics that could lead to relationship conversation. Delay it as much as possible and just use words like "hang out" when you see them again etc.
