So my boyfriend really likes tickling my feet and this is something that I really don't like. I've talked to him about it several times, but he just doesn't seem to be taking me seriously. When he tickles my feet he wraps his legs around me and holds me down in a way that I can't really do anything about it. When I asked him why he does it he said it's cute to see how much I try to defend. I've asked him to stop and he said he would, but hasn't gone through with that. I really don't know how to get him to stop, as it's something that makes me uncomfortable. I've even gone so far as to tell him to tickle me anywhere else (as I'm a very ticklish person). I know it's something he likes and thinks is cute, but I don't see why he won't stop even after my attempts to talk to him about it.
