Opperman et al. (2014) found that both men and women experienced better orgasms when they were comfortable with their sexual partner. This suggests that having a strong emotional connection and feeling at ease with one's partner can enhance sexual pleasure and satisfaction. Ignoring sexual preferences or engaging in casual sex relationships were not identified as factors that improved the quality of orgasms. refraining from sexual fantasies while masturbating was not discussed as a factor in this study.
