Yes, but sometimes it hurts if the ' love-tunnel ' is not relaxed & prepared beforehand and well-lubed right inside. A lot depends on your Lover. If you are ' shagged ' insensitively and too hastily with a long dildo it can be bloody painful. I would opt for a wide-diameter shorter dildo every time. Of course, you can't beat the real thing when you are turned on by someone who you really care about and who, yes, say it, loves you too.
Hot flesh is better by far than hard cold plastic anytime.
