I don't think it matters who does what first. It's if the other reciprocates that determines what happens next.
I don't mess around with the niceties in the beginning of a "might could be relationship". I almost point-blank ask their moral standards when we first get together. I let them know up front that we are never going to have any kind of sex not being married. Even at my age (50) I still have some who think I just "challenged" them.
I so want to be married. I do find interests, just not many. I've had one that was DETERMINED he was going to get me to change my mind and be with him. I tried, almost as many times as he tried. There was just something missing.
Just after Thanksgiving, I was pouring out my heart to one of my friends and she came back at me with such shocking truth that I was dumbfounded. She griped at me that she knows of 4 people in the past year that I have told her about that showed interest in me and I turned them away or ignored them or just acted like I was clueless of their actions. She has put me to a challenge and after a bunch of negotiating, we came to an agreement. For 90 days, I cannot turn down anyone unless I have concrete evidence they are not right for me. I agreed, because if I do this, she has agreed to stop smoking and start a healthy diet and to exercise.
She wanted me to let people know I am doing this, but I'm not. So far, I have said yes to one and I have a problem with him because he smokes. He doesn't smoke around me, but sometimes I smell it and can't stand it. I wanted to turn him down, but my friend said that wasn't a big enough moral issue for me to say no. He says he'll "go along" with the no sex rule. I know he's not a "keeper" like his grandma said she hopes we are. He's nice. He goes to church, he works for the electric company, he's 41, has a 20 year old son who lives in another state, going to college. This guy loves to indulge and that's just not me. In 2 weeks time, we have been out to eat 4 times, gone to the movies twice, ice cream places 3 times, to a small town to see their Christmas lights display and to see the Nutcracker. I have met many of his family members as we went to his Grandma's for her 80th birthday. We talk and talk, we laugh and laugh. We have a lot of things in common. He wants to meet my kids and I haven't even told my kids of him or my challenge. I don't want them to expect anything, or pressure me into something I don't want. I have told him my heart just isn't in this and he just says "well, we're havin' fun, aren't we darlin". I met him by opening the door for his sister who had her hands full and I was just walking past the building downtown that she was heading for. The very next day, I was walking to the post office downtown and she noticed me. She stopped me and told me she couldn't get me off her mind. That my opening the door for her was the nicest thing she can recall a stranger doing for her and that I must have a "heart for God". About 2 minutes into our conversation, she asked me if I was married or in a relationship because she had a brother she'd like to see with someone with "substance". (Fat on their bones???) I was in the process of telling her I wouldn't do that and wouldn't even feel comfortable doing that when my friend who gave me the challenge called me right then. No joke!!! I stepped away and laughing through my "right then" situation, my friend said "you don't believe in coincidence and you can't say no". So, I spent the next 10 minutes nervously talking to Rachel about me and her brother, David. 6 hours later I'm sitting in Outback with a nice, but complete stranger.
So, in my opinion, like I stated 8000 words ago, to me it doesn't matter who does what first, it's what happens next that counts.
