I like the first name 'Titouan' for a boy (French/celtic name). How does it sound in English?

I am French living in UK, so I care about how this name can resonate in a foreign language and especially if it can mean something negative.

As another poster stated, "tit" is a rather crude term for a breast. Just reading the name Titouan, that was the first thing I thought of.
Reply:"Tit" is a vulgar slang word for breast. You should keep that in mind.
