There's nothing "fundamentally wrong" with your sexuality.

Women wear lingerie, (coz we want to) you're not going to have to make "strange" requests when you're about to have sex in order to be aroused.
She'll get undressed, you'll see her naughty under garments, and voila!

What on God's green earth could be more natural and normal?

You seem dead set on wanting or needing to believe something is wrong with you, and your sexuality no matter how many folks assure you that your tastes are more vanilla than vanilla itself...

I'm starting to wonder if thats what's actually "fundamentally wrong" with you....
