Been dating for 2 months Birthday Present

[LanguageAsAFlower]

What's the etiquette for early relationship presents? Dating fairly casually for 2 months but definitely an exclusive relationship etc.
I know his hobbies but I don't know them well enough to know what a good present is and I want to make sure the present is appropriate for where we are. So he's a man, late 30s. Likes some niche books, works in education, bit geeky.

We’d been dating to months when it was my birthday and my oh got me a breaking bad mug (was favourite show at the time!) and a beautiful box of a expensive chocolates. Was perfect and not too OTT

I’d treat him to a nice meal out and a card.

Years ago I dated a chap for a similar amount of time when he had a birthday. I bought him a DVD of a film he’d seen recently and raved about, so the £10 mark. He was really cross that I’d bought him something and sent me an angry email. I was quite hurt and that ended things for me. Interestingly he wasn’t upset enough to give the DVD back so I could get a refund! Unfortunately it has made me very wary of men and birthdays.

How bizarre!
