<human>: Can you succinctly summarize the text in 1-3 sentences?

So I've been on three dates lately with three very beautiful women between the ages 21-27 who I felt like we'd had a wonderful evening and shared a lot of experiences that intrigued each other. I am 24. 

Each time, we have hung out, some I'd seen several times, one was a first date, but they all ended with us getting drunk and making out heavily and passionately. At the end of each, without my prompting, they'd said "I really want to have sex with you but I still like my ex/I have to go to my party/I need to go walk my dog." They'd all said they wanted to see me again, but to no avail. 

I never really hinted at sex nor was I looking (I always use a condom, which I didn't bring on purpose) and I'd never push for that so early in a relationship. I just would love to enjoy a second/multiple dates with one of these enticing women. What am I doing wrong, or is this just a "friend zone" for a guy they don't know too well and I'm just not that attractive?
<bot>: Why would women so cool with making out so much, be so hesitant to move on further, even if that wasn't where things were necessarily moving?
