A research conducted by American scientists who interviewed 171 heterosexual students below 25 years of age, found that men are more likely to speak about their feelings and profess love

Women appeared to be more cautious about expressing their love, whereas men seemed to have a hidden agenda behind their rather premature expression of love.
The best way to get women to bed faster is by expressing feelings of love and perhaps sexual desire is top of mind among most men. The study also showed that men could not differentiate between lust and love, and are rather confused about their feelings.
