Yes, sex!

It’ll be an overkill to begin to state here once again just how important sex – good sex – is between partners.

You could get it right in all other areas - and this is especially true for men - but failure to be on your A game during sex will leave a hole in your relationship, a huge blot on your credentials as a great partner.

If you fall into this category, your partner needs you to surely do better, whether she talks to you about it or not. She deserves it, and your relationship needs it to thrive too.

So why do you have to get better at sex for the sake of your relationship?

1. Bad sex, bad energy

Weak, bad sex creates tension between you and your boo especially when it is left undiscussed between both of you.

And by sex, I don't just mean the act of thrusting away. The whole package - foreplay, adventurous sex, new ideas, multiple new positions - all that good stuff.

If you are not varying it, you are not doing it right, even if she says nothing about it.

2. An unhappy relationship

Guy, if you are terrible at sex, your partner won't be particularly happy because frankly, sexual satisfaction plays an important role in the making of her complete happiness.

Forget it, gifts and other nice things can't meet this particular need. Nope!

3. She may cheat on you

And one more thing, sexual dissatisfaction is a legit cause of cheating among both men and women.

So don't give your partner a reason to consider seeking this satisfaction from someone else.

Get better. You relationship is hinged so dangerously on this.
