Foot fetishes 🙈😬

My man has a foot fetish. He loves when I have my nails painted and he like to nibble/suck on them during foreplay. Makes me giggle because I’m ticklish 😂🙈 I’m not in to it but he loves it so I let him. Before we moved in together, we would talk dirty about me getting him off with my feet.. but every time I try to touch his dick with my feet, he doesn’t seem interested?! So I just stop and blow him instead because he loves it. 🙈 I’m not very confident in bed with my body and what not but I want to fulfill his fantasies too. I’m just shy 😩😩 anyone have any good advice???
