Erm. no I don't think I have ever tried guessing. What's the point? It probably is possible to just glance and measure, but I think you'd be pretty obsessive to go around doing that to all you're boyfriends. I don't really listen if a guy tells me what size they are because quite often they exaggerate a bit, beside's I'm really not that bothered. Hope this helps.
