Whom you would go to so as to request to shave your back. If you are unmarried and are staying with family, it is your parents whom you may have to approach. However, your respect towards them would not let you ask them. All that you could do is to rely on your servant who may not have very good skills in shaving the back. Who comes next on this list? Probably friends with whom you stay together in a rented house when working together in an office. They definitely get busy with their own work and you may not get support from them. If you are married and want to continue to get this support from your wife, then it might be embarrassing. Unless she is very much open minded and understandable you would not be able to speak out this need of yours with her.
So, the best option is to stop taking the support of others and start using the back shaving razor that would be much comfortable. You do not have to depend on anyone else for your needs once you get this home. Having said this, you would be wondering if the cost of buying this device would overburden you in meeting your other needs. To your surprise you could buy it on your credit card as you buy any other product that is available on the ecommerce stores. You could also read the reviews and find out which best model would be available at a reasonable price. Once you have all these details do not postpone buying this device so that you could practice shaving your back hair with it even before you get married or before you move to a new state or country in the process of perceiving your career.
