The lovely and smart Anna King, a journalism student Columbia University, interviewed me and several other sex and dating columnists some time ago for an article. You can read it here.
Question:
Are there any tricks or methods, etc…. that can aid or assist in maintaining or extending the amount of time that a female is wet? Is there a specific length of time that female can be wet? Is this an individual thing? When she is "dry" is feels as if the her vagina is smaller/tighter (not sure if this is possible) or if her arousal "loosens" up the muscles within the vagina and allows for "easier access". Any thoughts?
Answer:
1) Generally, it is only excitement that extends natural vaginal lubrication, but sometimes even if a woman is super excited she may have reached her personal level of wetness for the day (there is only so much wetness to go around and yes it is individual). Other things can make a woman feel more dry, too, like if she is stressed, if she just had a warm bath or shower, or if she is taking certain medication (some birth control pills - probably particularly low estrogen pills - and antihistamines may be related to less vagina lubrication).
2) Not a specific length of time that I have ever seen.
3) Yes, dryness = more friction so things feel tighter. Wetness = more slippery, less friction, so things feel looser. Kind of like greasing a ring to take it off of a finger - neither the ring nor the finger change size, but it feels looser/comes off quicker. It is also the case that there might be some true difference you are detecting in that if a woman is super aroused, she is likely lubricating quite a bit (very wet) AND, as part of the arousal process, her vagina is probably tenting, which means that it is getting longer and wider, thus making room for penetration.
Oh, the wonders of arousal.
If you’re in a too-dry situation, you can add lube. If you’re in a too-wet situation, you can use a nearby towel or the sheets to dry things off a bit (you and her). Hope this helps

I often wonder what happens when women and men read my column and then…. what? As such, I really like it when readers follow up with me and let me know how things have gone with them.
Case in point: recently, in Time Out Chicago, a woman wanted advice on giving oral sex to her boyfriend, and yet including her best friend on it (apparently, she had been bragging about her boyfriend’s penis to her bff). Curious about what happened? Read the follow-up here.
In this week’s Time Out Chicago, I answer questions from readers about a partner grappling with gender identity issues, and to what extent marathon vaginal and oral sex sessions may contribute to yeast infections. Read the full column here.
Yikes! Vaginal cuts and tears from sex - especially non-lubricated sex - can hurt.
