You don't need it right now. If you die is anyone effected finacially? From your description no so you don't need any insurance. You only need insurance if your family or dependants depend on your for income.
If you are concerned about prices going up go check some online rate calculators. It certainly doesn't double at age 25. Also I would say that from your chosen field you would have at least the opportunity to purchase life insurance through your job in the future.
