In our experience his size only ended up being an issue for certain poistions. He was 10" and pretty thick. When it came doen to it she was so wet they didn't even need lube. After some warming up she was letting him,actually ordering him, to harder and faster! Just make sure he listens to your desires with positions/depth or else you take control. Unless your guy has severe elephantitus of the dick or somehitng I bet it will all work out
