From a guy's perspective, and my personal preference...yes. I dont like slurping or tacky ear work, but I think a nibble and bit of tongue action on the ear is a big turn on. Which brings me to another point ladies: I could never put enough stress on the importance of fore-play for a girl before sex. For women I think it is essential for them to having an orgasm. For men it is not generally. You touch it, its up..you know the rest. However, I think it is commonly over looked by women that it is still a major factor in the experience as a whole. Not enough women spend even 2-3 minutes with foreplay (neck, nips..etc). Just a thought. I know its the plight of the women around the world that men just jump into sex with no foreplay, but i though i should bring it up.
You know, another thing that is a big turn on for me (if not other guys) is fingernails. Fingernails, if you have them, can be a very delicate touch. I think i read it in some sex book somewhere but it said "fingernails are the copper wire through which sexual energy flows." A little deep if not overboard, but is has some truth to it. Take your nails and draw them lightly over the inside of your lover's thighs and/or stomach. Nice feeling.
It's a major turn on for me, I lose control of all of my senses. But slurping is a bad idea, any loud noises are. Can even make someone go deaf with a loud smacking sound.
Yea, totally a turn on. Around, inside... nibbling, it's all good. Especially if you have piercings, can give it a tug.
i get a boner within seconds when my girl puts her tongue in my ears. its amazing. When i'm going down on here she grabs my ears and uses them to pull my head around, it makes me so freakin horny
