1. Anal sex Anal sex gives a different pleasure compared to regular sex, and it's getting all the more common these days with couples, but you are advised to never shock her with it. There are women that don't get aroused by anal stimulation. So men should always know what kind of women they are in bed. If it has been a bad experience in the past, she'll be off it for the rest of her life. 

2. Getting pregnant Men always prefer sex with their partners without a condom. But it's a headache for women if they are not ready to have babies. Having sex and pulling out before ejaculating may not be the best way out. And women don't like to take birth control pills or pregnancy test all the time. So men should never impose unprotected sex on their partners. 

3. Extreme sex Before you experience kinky sex understand your partner well. We know sex toys, handcuffs, ropes, satin ribbons, dirty talks, and whips are a great stimulant, but not if you are using them at a wrong time or with a new partner as it can scare the hell out of her. So, stop acting like a porn star! 

4. Sex during periods It may be okay to have sex during periods but women always feel uncomfortable or unsafe while doing so. Sometimes it becomes messy and turns out to be a big turn off. So be patient, wait for the monthly break to be over and enjoy smooth love making. 

5. Sex with no passion Sex without love or passion happens only in porn movies. Men can do it but women can't. Jumping into the bed without kissing your partner or doing a little warm up to arouse her will make her all the more uncomfortable. Don't forget that women always associate sex with love and emotions.
