Sex on a holiday allows you to get away from pressures, distractions, worries and responsibilities - basically, any of those libido-killers that affect your love life most days of the year.
While on vacation, you can totally devote yourself to nurturing your sexual needs and desires - and to attending to those of your lover.
This is one of the reasons the vast majority of American marriage counsellors recommend a regular weekend away as the one thing that can help a marriage, especially a struggling one.
Vacation is the best place to get 'sexperimental'. People love having sex in new places. This is in large part because of the neurotransmitter dopamine.
When people have new experiences, dopamine spikes in the brain, triggering lust. And with that, many are willing to try something new and exciting.
In a new, romantic, or exotic place, lovers can rediscover one another. In trying different restaurants or embarking on a variety of nightlife activities, every evening that you're away feels like a date night, each with its own distinct backdrop.
All of this enhances lovers' moods, helping them to feel better about one another and more connected.
When you make the time for nothing but loving, that's hopefully what you're going to get - and lots of it.
Sex will breed the desire for more sex, making both partners feel better about their sex life and the relationship.
This is both for couples already content with their sex life and those hoping their vacation will make for some romance repair.
