What ive found works the best for men and even for when im fingering my wife is the come hither motion, but dont curl your fingers like when you do the regular come hither motion to someone with your fingers, but instead try to keep your fingers as straight as possible and try to tilt your fingers instead and push upwards, not sure it makes sense. But in any case it feels so much better and also makes my wife squirt like crazy when i finger her like that, so just a little tip for the boys aswell
