i can relate. i have a long distance bf, so we see each other less than a month a year. But whenever we're together, we have not very much alone time together, and when we're alone, we rarely gets to have sex. And when we get to have sex, sometimes he can't get it in... i don't know why... maybe he's too nervous. ~.~
Not to mention the other 11 mths of a year i don't get to see him and have zero sex life. >.>
