New boyfriend pick my lingerie?

So I've got into a new relationship (2nd serious relationship ever I'm 31) with a very down to earth guy he's funny kind and caring we have been officially boyfriend/girlfriend for about a month now and we have had sex twice.

The very first time it wasn't too great I forgot to tell him I am allergic to latex and so the condoms I was were too small so he couldn't get hard. I was kind of upset it didn't go well... and thought wow I've shared myself with someone and it didn't go well.

Second time... Oh My goodness I was pleasantly surprised! Wild fun sex! So releaved! Now we are planning for the 3rd occasion... I asked him what colour lingerie he likes, assuming he liked colours but he said he only likes black lingerie and he's not into colours at all.

I feel a little disappointed I like wearing colours makes me feel sexy and confident but just black? he said red only for valentines day...🥲

Why does he like just black?
Anyone persuaded their lover to like colourful lingerie before, how did you do it?

Also was worried it if it's too soon for me to ask him what his preferences are? I do want to please him as he pleases me very well.

Great suggestion on how to try and persuade him on the colour choice I like it! Yeah I agree I am putting too much focus on this aspect of our new sex life.
