- Find out exactly the kind of high heel shoes he likes. For a fetishist there will be a certain type of shoe that turns him on and probably many that don't. Things like glossy, platform, open toe, height will all be factors. Some guys like trainers, some like boots - it's a complicated area to know what exactly triggers him without talking.
- If at all possible, find a way for the shoes to not only turn on your boyfriend - find ways that they turn you on too. Perhaps rubbing the toe or heel against your clit as a way of masturbating. Your boyfriend might not want to lick his own cum from your shoes but I bet he'd be excited to lick your juices from them.
- For positions it can be hard for the guy to see the heels in most. Here you can help by simply just moving your legs or feet to places where he can see them - you can do this in most positions. Grabbing your heels while having sex really helps and will almost certainly make him happy. If you think of the heels to make your boyfriend harder and more passionate then the more you interact with them the more turned on you're going to be too.
- Remember, what you have is a man who will be attentive, a better lover, harder and more devoted if you can learn to love that he gets turned on by this.
- From the sound of it your boyfriend would love it if you asked him to slide his cock between your heels. If he's like many of us though he might not want to see or have contact with your bare feet - I personally find them horrible - that's why I have a shoe and boot fetish lol. Key thing to remember is that from what you describe you're boyfriend has a fetish for feet in heels - not feet with heels.
- Don't know if you watch porn - if you do then find some clips involving heels that turn you both on - again it's about you getting something out of it too.
Hope some of those ideas help
