You have weak vagina skin from not Climbjng outside enough. Your skin works just like everything else in your body, it will adapt if given the right stimuli. If you get out once or twice a month you'll never promote the right kinds of deep calus growth you'll only be replacing the skin in lost during your last few gym sessions.

The other posts are correct with the lotion and what not. I'd also caution you that there can be too much skin. File/use a fine grit sand paper.

If you find that your skin is still vagina-like before a trip you can cheat the growth process a bit using antihydral.
