<human>: Can you provide a brief overview of the text?

I am a 27/f who recently in the last 2 months got involved with a long term friend 25/m. We have had an amazing friendship for almost a year, recently he expressed his interest in a female lead sexual relationship.  That being said please do not refer me to BDSM or sex I promise thats not what this post is about.  Our relationship was about a lot of open communication and trust because he is not open with people about his desire for a female lead relationship.  Anyway,  about 2 weeks ago I was talking with a friend of mine and the word couple came out of my mouth.  After that she started talking about how different we both were after becoming involved and how most of our mutual friends had noticed.  After talking a while I realized that not only was I happier and more fulfilled in our relationship than I had been in any previous but also than I had been alone for 2+ years but I was actually falling in love with him... Damn it L word you ruin everything

Fast forward through the awkward "umm so I have something to kind of tell you" moment to his response.  I am not "that" kind of girl to him... I asked him what that meant and he told me that we dont have an x factor.  He has however said that he cant imagine not being with me he counts down the minutes till we are together calls first thing in the morning we talk for hours about nothing sexual and we have an amazing sex life seperately.  So it brings me to wonder What X factor is he looking for and do I just give up?

He is not much younger than I am but he is much less experienced in life "see Sheltered"  We have different backgrounds but similar goals.  I am just in need of some advice.
<bot>: I am falling in love with my FWB dont want it to end but he says theres no x factor... Now what
