May I suggest the possibility that these women are simply reacting to what you’re saying (that most women like it) and don’t want to be viewed by you as a weirdo. And/or feel pressured by you because you treat it like it’s nothing, so they feel they should too. And/or are slightly intoxicated (you mention picking her up at a bar). Every now and then, yeah, you’ll come across a woman who asks for it or heavily implies they want it. But it’s far from a ‘staple’. My suggestion to you is to either wait until they ask for it or wait until the relationship is strong enough for you to ask (and be fully prepared for a ‘no’). Generally speaking, sex for women is much more emotional and there needs to be a strong bond before you go down the dirt road. But it doesn’t sound like you’re taking advice.
