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

Dating for 4 years, living together for 2.

My boyfriend and I have had a steady and satisfying sex life since the beginning. However, everything changed around December 2014. My dad was hospitalized the entire month and my boyfriend was by my side through it all. My father eventually had to go on life support and my family and I made the gut-wrenching decision to take him off the machines the day after Christmas.

Needless to say, the entire month of December was a shit-show emotionally. My boyfriend was with me for it all, and I don't think I could have gone through this horrible time without him.

We were both deeply affected by my dad's passing, so naturally, our sex life was non-existent for a few months.

It's now May, and my boyfriend has just started showing interest in resuming our usual, playful, fun sex life. We tried having sex the other night and I just felt numb to it. I hate to say it, but it felt like kissing my brother or something. I couldn't get into it, and he just ended up finishing himself. He wasn't disappointed or mad at all, he understands that this is weird time for me.

I can still get horny when I'm alone and satisfy myself thankyouverymuch. It's just that I can't get into it with my boyfriend at all.

My question is: has having my boyfriend around for all this heart-crushing, emotional shit killed the "mystery" that I think makes sex exciting? Does knowing someone *too* well change the way you relate to them sexually? I would love to hear what the older, wiser crowd has to say about this. If you've been in a similar situation I'd love to hear your story. Thank you.
<bot>: BF and I have a good, regular sex life until my dad's passing. Now I can't get in the mood with him anymore.
