It had a nice pacing and I did like the main characters.
It kept me reading and interested very much until the 2/3 mark.
Then something threw me:
the whole No-Sex thing. I really didn't get it. The reasoning with not wanting children now, is not exactly convincing as there are options to be nearly 100% safe. And so it really read more like a friendship story than a romance.
There was zero sexual tension. Zero, zilch, nada.
And that felt very strange.
It didn't bother me, that it was a clean romance - I do like them, but I missed passion. It felt somehow lifeless. The way two adult people are in a romantic relationship and no one is tempted to do more than cuddle and kiss. No petting, no touching, nothing.
So there is no believable (at least to me) build-up.
And then the cheap shot in the end - the wedding. I guess they will have sex on their wedding night, but guessing is all the reader can do...
