This question is essential and it is one that many people struggle with.
What is the best attitude towards sex?
Is it better to put a lid on it?
Or is it better to use it and master it, creating beauty and love?
Again, you are free to choose what suits you best.
You have so many different approaches because different people have different needs.
Sex is beautiful!
If it wasn't for it, there would be no life on this planet.
How could the act which creates life be condemned?
Again, this is only one opinion and you are totally free to disagree with this statement.
It probably means that for you, sex doesn't have this dimension of sacredness and tantric sex isn't a stream you want to engage into.
If you struggle with your sexual energy and trying to suppress sex didn't work too well for you, then tantric sex is definitely an option for you.
In my own experience, embracing and using your sexual energy rather than trying to put a lid on it is a very powerful transformation tool.
Again, you are free and you have many possible ways to go.
Tantric sex is only one of them.
To your limitless freedom!
