Woman Turned On By Guys Wearing Panties

I've heard about woman getting their husbands and boyfriends to wear their panties. I'm interested to get my boyfriend to do it, I have seen pictures of guys wearing panties and it turns me on and I know seeing my boyfriend wearing panties would excite me, just not sure if wearing panties would excite him, by what I have heard many men who slip them on wonder why they did not do it sooner.
