The following seemed obvious to me.

How should I deal with my very high sexual libido?  My spouse and I live in different places (Too far!) due to our professional commitments and we meet just once a year for few days only.  I am in my thirties.  What should I do?

In your case, don’t worry about the practice of my suggestions. Consider the purpose of them.

If you can keep the following secure and private between each other, may I suggest …

  1. Phone sex?
  2. Sexting?
  3. Dirty pictures of each other?
  4. Writing each other dirty stories and sending them via old-fashioned letter and stamped envelope (that you perfume)?
  5. Touching yourselves (in private, of course) as little or as much as you’d like?
  6. Buying an array and assortment of sex toys?
  7. Seeing other people (if you’re both non-monogamous and have honestly and ethically established your boundaries ahead of time)?
  8. Scheduling as many “sex dates” as you can once you finally do meet up?

I could go on, but you get the picture (figuratively and literally).
