All sorts of relationships have their advantages and disadvantages. If you are dating seriously that too may have its ups and downs. Just like any other relation dating casually also has its positives and negatives. Let's first discuss some of the positives and then the negatives.
Many people believe that friends with benefits is mutually beneficial for both parties, not only when you are young but also when you are old and you want to avoid commitment. In general when women become old they are not lusted or desired by their husbands any more. This might be a good thing for those deprived women. The first advantage you have is that you have a friend.
As the name suggests Friends with benefits, you have someone you desire and at the same time someone you trust. You can share your all day's worry with them. You have someone you can confide in. The best banter you can have is with the opposite gender. A friend with benefits is someone you're attracted to, generally someone you like, and someone you enjoy having sex with. He may have started out as a friend and the magic isn't there, but you have a great time together — especially in bed.
The sex is fantastic with a new person. Who doesn't feel great and glorious after a great intercourse. All of us want to enjoy the flirtation and the tingling feeling you get when your partner is on top and he touches your buttocks. You can do all sorts of experiments which you could not do with your wife or husband if you were married.
If you have never been married before this is a great way to practice safe sex for future serious relationships. If you are good in bed your wife will never leave you. Also a lot of women hesitate before trying out new things. This is a fantastic way of experimenting new things. Sex in itself is a gift from god. People who don't get jealous, don't associate love with sex, don't fall head over heels for sexual partners, don't have romantic feelings, this is best for them. This way of life gives you freedom to express yourself and you sexual life like never before. People who get accustomed to this sort of life never let go of it.
Like any other relationship, friends with benefits may also have some negatives. This is not a configuration that is suitable for everyone. If you easily get attached to people, are emotional, associate sex with love and fall in love easily with sexual partners then this is not your cup of tea. Don't try to do it just to look cool in front of your friends or circle. This is just not for everyone. Sometimes you don't even realize and you are past the point of casual dating. You just want something serious and meaningful in life that is when things can get awkward. Your partner might not like dating you seriously where as you heart might be home to them.
Friends with benefits can also be expensive to maintain. Such a life style can be extremely expensive to afford and you never know when you have to spend a 100$ on a night out at a pub for enjoyment because she wont meet you otherwise. Such relationships can be draining your income. Apart from financial costs, what if you get attached. It will be heart-breaking as the other person not agree to commitment which may lead to disappointment and pain.
