Have you heard of the ‘bi-cycle’? By definition, the ‘bi-cycle’ means when people (not just bisexual people) find that their sexual preferences change from day to day or even minute to minute. It’s perfectly normal for your sexual desires to fluctuate throughout the month, but also over the long term. What you enjoy today is different than what you wanted five years ago and this is what keeps sex so exciting.
Many cis and trans women report that it’s not only their sex drive that fluctuates with their menstrual cycles (as reported in earlier research with regard to ovulation and sexual interest) but also their specific sexual desires and fantasies.
For example, many of the women I work with who are in CNM (consensually non-monogamous) relationships report that their interest and comfort with the CNM component of their relationship dips right before menstruation. This could be attributed to hormonal, but also to shifts in mood, energy levels and body image during the pre-menstrual phase of their cycles.
Other women report that their sexual fantasies change with their cycles. One client says that she likes rougher sex during the second and third week of their cycle and prefers more intimate, romantic encounters during the first and fourth week.
I have some clients that find that their desire in terms of gender is fluid — sometimes
