Search Results: he is not interested in sex anymore

A few years ago I used to ask questions on here about my coworker. We no longer work together but he became my closest friend after I quit. I used to show him dirty pics of me & tease him at work. I was never shy about telling him I liked him so he's always known.
He came over to hang out at my house one day last spring. We hadn't seen each other in a while so we watched a movie & caught up. Mind you he showed up around 11 pm lol. After a few hours I sat closer to him & made a move. He totally went with it. We had sex that night he left around 6 am. After that it became a regular thing.
He's a guy that doesn't show much emotion or affection & doesn't like to get close or open up. When we were together alone he would tell me everything in confidence. We would laugh & play around. He hates kissing but he loved kissing me & holding me in his arms. Kissing my neck & forehead too. He made me feel like I was his. He did everything with me he had expressed no interest in. That made me feel so special.
This April I couldn't hold it in anymore & finally told him I honestly like him & that I want to be with him. He said "we can't mess up our friendship". I backed off & didn't see or talk to him until the end of May when he randomly texted me. It took a few days but we've started talking almost daily again & hints at how much he misses me (sex). I want him too but I'm making him wait.
He has apologized a few times but has never expressed any change in his feelings. I'll ask him to come over so we can talk soon. I know it's obvious that he wants the sex back but is there any chance that he may like me? Every time we talk he flirts with me or calls me cute, adorable, etc. I just can't seem to let him go. Sex has definitely made things more complicated. I want to be with him but I hate getting my feelings hurt.

I read somewhere that part of the reason women are having such a hard time finding decent men is because we as women don't demand that they treat us right. Like say after 2 weeks of dating that a guy wanted sex and the girl didn't. If he announced he was no longer interested, then she'd have sex with him to keep him interested instead of taking it as the red flag that it is: he just wants sex. Basically they were saying that we as women don't treat sex as a luxury anymore when it actually is in a relationship. Instead, we hand it out like candy which is why men no longer feel the need to value us for our personality or other offerings. I don't have the article though because I read it at the library.

Here's some quotes from a different webpage by someone named Evan Katz:

"My advice is not to tell men that they shouldn’t sleep with women; it’s to tell women that you must have men make a greater investment in you as individuals before having sex... You want to find out if a man is serious about you? Wait to have sex with him. If you don’t – because you’re a liberated woman who can have sex whenever you damn well please – don’t be too surprised if a decent percentage of those men never call again. Again, I’m not remotely judgmental of those who have sex without commitment; I will only point out as a dating coach that it tends to lead to sub-optimal results from men because they didn’t have to do anything special to get into bed with you."

So what do you think? Is the reason dating is so difficult these days because women don't make men value them as people?
