Objective  To examine love attitudes and psychosexual health among undergraduates in Hainan province and to provide an assistance to the undergraduates to acquire correct cognition on the issues.

  Methods  We conducted a self-administered survey among 1 294 undergraduates recruited with stratified random sampling from 3 universities in Hainan province from February to December 2017 using a self-designed questionnaire.

  Results  Among all the participants (623 48.15% males and 671 51.85% females), 58.66% reported being in love (29.37% and 29.29% with previous and current experience) and there was no significant gender difference in the proportion of involvement in love affair (P > 0.05). The participants′ love attitudes and psychosexual health differed significantly by gender. Sexual desire was considered as the most important factor for a love affair by 16.53% of the males but only 4.92% of the females, with a significant difference (P < 0.05). There were totally 20.00% of the participants reporting the history of having sex and significantly more male than the female participants reported sexual behavior history (27.93% vs. 12.97%, P < 0. 05).

  Conclusion  For the undergraduates, the males have more diverse ideas on love attitudes than the females; while more females have conservative consideration on chastity than the males.
