Being a virgin at 25 is not really ok, people need to stop selling the OP a crock of ****, it won't help him.
No male wants to be a virgin at that age, if you are, it's a symptom of a deeper problem, which you recognise is not to do with your looks but your lifestyle. This can be changed over time, but whatever happens, you really need to understand that there is yet more to life that this, and under no circumstances should you think your situation warrants a self-inflicted death penalty. It absolutely does not. Even if you never have sex - which would be unfortunate - you have a large chunk of life's pleasures remaining, why lose out on the rest of it?
