I'm similar age to you and have had multiple girlfriends who I met at school uni, but now that I'm out of uni I'm finding it particularly hard to meet girls (romantically or platonically) because of the stutter, i feel your pain it's hard to talk in a group and then you don't seem to meet people... online dating is a good way I think (I hate it but it's the world we live in lol), I just always say before we meet up "btw so you're not surprised I have a stammer" and have never had a bad reaction on a first date!
