Fetish?

I recently started getting naughty😏with my bf but before this, we had spoken of our sexuality and what not and he confessed to me that he had a foot fetish. I personally dont think its a big deal at all and in fact it's very common among men. However, its been a VERY LONG since i had sexy time and i used to be so good at it but the thing is its not working going as i thought it would. I used to be great at sex and now idk why but his fetish changes everything. Im not uncomfortable or anything but honestly What do i do? Any tips ? Does your man have one? Help 😩
