Interesting question and a conflicting opinion.

I keep hearing that being bad at sex will result in your girl leaving you.

Read a book recently, where the author said he would emotionally connect so well with women, that even if he didn't do an absolutely amazing job at sex, they still wanted to be with him. Said that sex guides were a bit over-rated in usefulness.

Let's say you do a great job of emotionally connecting, and then you do an average job at sex, in other words not a failiure but nothing spectacular either...Would this lead to success?

Success in what? This question doesn't make sense.

If you're in a long term relationship, sex is something you can get better at while you and your girl explore / improve.

A girl can leave you for many reasons. Theres more to it than emotionally connecting. Guys who are friendzoned emotionally connect well but they never get sex. Be careful of what you read into, balance is key. Being a sex god isn't a bad thing either. If author is saying sex is overrated, then he has other issues to contend with.

Assuming we're talking about leaving an LTR or something developing into an LTR...

Avoiding extremes of good/bad: Emotional connection > sexual prowess.

First of all, strong emotional connection with a girl can make sexual activity completely effortless. As in, "she-basically-initiates" effortless. There's also the sexual attraction component which needs to be present, but it becomes much more powerful with emotional connection (in my opinion).

If you have good emotional connection and average sexual performance ... you should be OK.

And it's all relative, in practice. If her previous guys really sucked in bed, then a true "average" performance from you might seem amazing to her, and vice versa.

That being said, if you have a micropenis or last 2 minutes in bed - then you have a potential "extreme" performance problem and she might run off.
