I'm a 27 year old male. I've never had sex and I've never kissed a girl. I have shaken hands with girls, though

No, I'm not asexual. I'm a straight guy with a an extremely high libido.

Long story short :
1. bullied as a kid -> became a loner -> depression, anxiety, OCD -> angry at the world, hatred for human race, hoping for giant asteroid to hit earth
2. Extremely unattractive : short, thinning hair, no blue/green eyes, no cute face with amazing features, no milky white smooth skin, hairy chest, slightly hairy back
3. Small Penis
4. Raised by parents who are big fans of ethics/morals/values and all that jazz -> I feel very uncomfortable doing things that society considers "immoral" -> prostitutes not an option

I'm not looking for help getting laid.
And please, do not start with that nonsense about how there's someone out there for everyone and that I just need to have faith and patience. If that's all you've got to offer, please do not reply.

My questions are purely scientific :
1. Are there any adverse physiological effects on not getting any sex even though you constantly desire sex?
2. Is masturbation a complete/perfect alternative to sexual activity with another human being, as far as physiological effects are concerned?
3. If not, are the adverse physiological effects on not getting any sex serious enough to affect a person's well-being (sleep quality, general health, immune system, efficiency at job, etc ..)?
