 women start to become perimenopausal as early as the 30s more commonly in their 40s it's just something to think about i want to dive a little bit more into that research but what we do know is that contraception impacts pheromones and the type of person that we're interested in dating and so i do i just have to wonder if some of these trends also influence the fact that the vast majority of people who are in the dating scene are heading into that 30 40 range rather than in the 20s
