Being in a long-term relationship is great, but does that mean you have sacrifice on passion? Studies have shown that relationships tend switch from passionate to compassionate after a period between 6 and 30 months. That's the time when couples usually get comfortable (sometimes too comfortable!) and hot sex might take a backseat in the relationship.

But that doesn't mean you can't keep the embers burning. Just make sure to heed the following mood-killers in the list below which can be a major turn-off for your lover:
Ignoring Her Appearance
The female sexual desire is tied to a sense of self-esteem. But guys in long-term relationships tend to stop noticing when their partner looks pretty. Try paying her a few simple compliments every day to let her know that you still find her sexy.

Putting Her Under Pressure
Good sex is about connection and sensual satisfaction, not number of orgasms produced. Keep it relaxed and focused on playful touching, taking off the performance pressure on both of you.

Using Porn As a Benchmark

While it's good to spice things up, it’s more important to keep it real. So while pornos might look hot on film, that doesn’t mean it’s safe or satisfying. Plus, it might not even be something she’s into.

A desensitized brain can also find normal sex less arousing, so if you've become accustomed to extreme stimulation, then you may want to cut back on the porn viewing. This will help restore your brain to normal sensitivity, allowing normal sex to be enjoyable again.

Leaving Her Lips Hanging
Unlike guys, female desire doesn’t operate like a light switch that turns on and off. So foreplay should be more than just a precursor to sex. Focus more on small acts of intimacy (hugging and kissing) to get her in the mood. And remember to be patient about it!
