I disagree. In the last six years, every women I dated for 6-18 months I slept with on the first date, second date, third date, or fourth date. For each of these women, I covertly extended the offer from date #1, so clearly the covert extension of the offer did not negatively impact my subsequent experiences with them. If you follow my guidance on making the invitation covert, deniable, and you do not push if she declines, then it does not come off as too strong - because it is deniable. You aren't offering sex. You are just inviting her over and presenting her with the opportunity to decide if she wants to have sex - covertly.
Your comment about fishing for trout in swamps and previous comments about aggressive women with caked-on makeup makes me think you are seeing women as black and white - they are either slvts who fvck on the first date or they are "quality" women who won't sleep with you until marriage, or somewhere between date number x and marriage. This is a common blue-pill misconception. Women are guided by their emotions. Push the right buttons and they will want to sleep with you on the first date and lock you down into a relationship shortly after. Even if they choose to hold back on their urges and resist temptation of first date sex, you still lose nothing by extending the offer, but you can lose everything if you don't.
Another point to mention is many LTR-focused women will say they they "aren't ready for a relationship right now." What that really means is they just haven't found a guy who pushes their buttons. One of the strongest buttons to push with a woman is NOT giving out relationship vibes, while also not giving out player vibes. You do this by following what I describe above. Your attitude should be, "I like spending time with you, I like having sex with you. I'm happy just like this and need nothing more," but without communicating this to her directly. You simply set dates, show her a great time, enjoy it yourself, and provide the opportunity for sex. Rinse, repeat. This drives women mad. It quickly turns a woman from "I'm not ready for a relationship yet" to "I want to lock you down." And if it doesn't? You lose nothing. You had fun with a girl for a while and had some good sex. It is all part of the journey. Again, this is red pill 101. Date casually, see what happens.
Avoiding sex with women is never going to serve you, or her for that matter.
