Husband asked me not to "play" with myself..

So last week we sexted the whole week and sent videos to eachother and whatnot and it was super hot..

But out of no where last night he told me to delete the videos and I texted back "but what if I need them ;)" and he said "you can wait". He went on to tell me not to masturbate anymore and if I get horny just wait until the next time he sees me.

Liikkee.. wtf? Btw, he's been working out of town for the past couple of months, reason why I don't see him except for every other week. But why would he suddenly after all this time have a problem with me masturbating? I asked him and he wouldn't give me an answer.
