I was trying to convey the idea (perhaps with too much cleverness) that while using the rear entry position the man might be supporting himself on his two knees and on one of his hands, totaling three points of support. I was answering a question about which position was best for women to receive manual stimulation during intercourse. You talked about a woman being on 'all fours' and a man being on 'all threes.' We have been unable to figure out which (or what) three?Ī: In mentioning a man being on all threes I may have confused more folks than you. Q: We have a question about a past column in which you were writing about sexual positions. One common problem is an inability to insert very far without causing pain to their partner. The small percentage of men whose penis is that large often have difficulties in creating satisfying intercourse stimulation for both themselves and their partner.
