My [28F] boyfriend [27M] barks like a dog during sex. I’m finding it very off-putting and don’t know whether to end things?

Some quick context – I’ve been together with my boyfriend for nearly 7 months. When the pandemic started, it made sense for him to temporarily move in with me as I have a backyard his two dogs can use.

So when we first got together and we’re physical for the first time, my boyfriend liked to make “growling” noises. He also makes them when he’s feeling in the mood and wants sex. He also likes it when I scratch his back, and he likes to bite my skin too. I found all of this was a bit intense at first, but I soon got used to it and we both found what we were comfortable with.

Since he’s moved in, he’s started coming onto me more often by “growling” seductively I guess? If I’m too tired he’ll whine – like a dog – and give puppy dog eyes. I laughed at him the first time this happened and he didn’t go any further as I wasn’t budging.

The second time gets a little stranger. He started the growling again, nipping my ear and when I resisted he whined and started pawing at me. Yeah. I told him I found the behaviour very strange. He just giggled and then tried to dry hump my leg. Sigh.

So this behaviour has escalated over the last month and a half. I’ve tried to ignore it and for us to go straight into having sex so he doesn’t do any of his “doggy behaviour” and for about 2 weeks it was okay, until the last three times we slept together.

When we sleep together he literally barks out loud with every movement and when he finishes he howls. Literally howls. By this point I’m done.

I got really frustrated last time this happened and we haven’t slept together since. I’ve asked what on Earth all of this behaviour is about. He denies it’s a fetish and it’s just a bit of fun, but I think it could be? I honestly don’t know. I’ve told him many times I don’t find it attractive but he still keeps doing it.

My friend said he could have a secret fascination with furries? Do furries do this?!

Also, should I be worried about his 2 dogs?!

Please help!!

TLDR – boyfriend acts likes a dog when he’s horny and barks when we sleep together. What do I do?!
