Hot dog is an intercourse position which is too acrobatic for most girls. You must be very loose-limbed to stretch your legs like that.
For easy access of the penis the girl has to find the right angle. She must decide how far she has to tilt her pelvis upward. In the right angle the penis can penetrate deeply.
Because penetration is very deep the guy can easily hit the cervix, which some girls find painful. This demands restraint, especially during his climax.
Not a good position for stimulation of the clitoris. But the glans penis is strongly stimulated. So this position offers the guy more sexual stimulation than the girl. It’s not a good position for guys who have difficulty delaying orgasm.
