Am I doing something wrong?

I am 25yr old asian female. I got out of a 7 year relationship with my ex. I have never went to a casual date until i met a guy, lets call him-Sam.. He came over to my home to do some tasks. I was being nice to him and given my friendly nature i was talking to him. He is really tall and cute, has a great smile.. but thats it I never thought I was flirting, until someone pointed it out to me. While he was leaving he asked for my number Again, I have never went to a casual date or met someone casually like that, and i got out of a relationship 7/8 Months prior to meeting Sam after pausing for few seconds I gave Sam my number, because I thought maybe it wont be a bad idea to date alittle. We were talking for a while then he wanted to grab some coffee. So we grabbed some coffee, walked around talked and we went to several dates and we used to text all the time. Even though we went on several dates we never kissed or held hands.. I was waiting for him to make a move but we just walked around talked he mentioned his Ex couple of times as his Girl or watched movies at the theater or had meals together…As I used to pay for my meals in my past relationship, i was paying for my meals and sometimes sam’s too when we went out on dinner dates. On our last date, it went really good according to me and I was kinda waiting for him to make the move but he just dropped me off at the train station and we went our own ways.. after few days we have been talking but the conversation were getting shorter. One day he was telling me about his hook ups and honestly I dont mind about his body count because I feel like people have their own experience and journey, and he asked about me and I told him it was One, I told him that’s because I need to have some kind of emotional connection with a person for me to be physically intimate. And the next day Sam and I have been texting but short conversations, he didnt seem interested so I didnt push it. I was acting normal and then he stopped texting me and ghosted me. My friends keep saying that its because there wasn’t any intimacy and the fact that I told him I need emotional connention to be intimate. I have been very insecure about myself after my last relationship so i didnt know if I was behaving how people usually behave on a date, I tried being myself My question- Is that really true? Like is it because I told him how I feel, scared him off? How do you act on a date even? Am I doing something wrong? Can someone help me? I feel like insecure and that something is wrong with me because of my past experience and this one too.

Sorry! my english is not that great so please excuse the poor grammar.
