Anytime I have been single, I welcomed/expected to discuss it or more than likely, at least talk about sex alot as flirting before actually having sex.
I am ashamed to say that when I was married, I remember expecting sex much more than I had sex with my ex. Probably due to lack of communication, so...
I believe that the feelings of fear of rejection or having insecurities isn't a female issue as much as it is whomever in the relationship has the least self esteem, so your topic seems to insinuate these feelings and fears are only on the female side, but could be on either ide in my opinion.
Either way, communication is very important.
