Given that men likely don't understand this need, I'll break down the benefits snuggling brings to them in a logical fashion. Regardless of whether you get it (our need for intimate snuggle time), you should give it (those damn snuggles) and here's why.
Snuggle Time = Sex Time + 10%
It takes a mere 2 to 5 minutes, 3 to 4 times daily to meet your cuddle quotient. That is 6 to 20 minutes throughout the day to ensure a happy girlfriend. Happy girlfriends show their appreciation.
Your average 13 minute investment on a daily basis can accrue by 10% over a given time period. You've invested 65 minutes total by the time the weekend arrives. Your snuggle stock is now equal to 71.5 minutes in sex currency. Cash it in all at once or disperse the earnings over a two-day time frame, the choice is yours. The important thing to remember is that you now have options.
Timing is key - snuggle stock plummets and is long forgotten after 5-7 days. It runs on a weekly cycle so it is important to buy, buy, buy then SELL when the market is ready.
Obviously, do not tell your girlfriend (who is delighted by your recent attention and affection) that you are doing it for yourself. This backfires and you'll lose your worth completely. Keep the calculations in your head and take your earnings to the bank, or rather, the bed, when the time is right. While it may be for different reasons and in different ways, snuggling can be just as valuable to men as it is to women.
