<human>: Can you condense the text into three sentences or less?

So after moving to uni, I met this amazing girl who I became attracted to after the first few times we hung out. The only issue is that she was having issues with an ex that also lives on the same campus (unresolved feelings etc) and she confided in my about this (classic friendzone right?)

She ended up clearing up her feelings for her ex, and we discussed our feelings for each other. We spent minimum 2-3 hours together/day simply because we get along so well and we live in close-ish proximity. 

However after staying over at hers for the third time last night and escalating things to the point of sex, she told me she was confused about the sexual chemistry between us. 

I believe that because of the uncertainty about her and her ex in the early part of our friendship/relationship I stalled building any sexual tension/whatever because I didn't think she was available. Now I am at the point where we are at the overdue point of having sex and she is confused about our chemistry in the bedroom as that didn't exist when we were friends. 

Obviously sex is a huge part of  relationships and I want that chemistry/tension to exist so that we can explore our feelings for each other further.

Did we surpass the point of building sexual tension while we existed as friends, or is there still time to work on it?
<bot>: Female friend of two months cleared up ex issues and admitted feelings for me, but is confused about sexual chemistry as we were friends for some time before escalating things?
