Your sexuality is separate from your partner’s sexuality

Fun fact: Your sexuality and your partner’s sexuality are not the same. Of course, they influence and shape each other. Your sex life is the point where they intersect. But that doesn’t mean they cease to exist as separate entities. Just as you are an autonomous being and continue to have your feelings, thoughts, and emotions, your sexuality also boils up independently.
Moreover, masturbation is one of the best ways to understand yourself sexually. Without pressure or expectations, we can discover what works for us, what we like, and what doesn’t feel right for us. Whether you’re sexually inexperienced or constantly rediscovering yourself, there’s nothing better than being alone to get to know yourself and ultimately improve your sex life.
Sex toys are great for self-care
For some people myself included), sex toys are a little moment of relaxation, a cathartic cleansing of everything. For others, it’s a luxurious and elaborate experience. For some, it’s almost mindfulness. Whatever adult toys are for you, they’re wonderful and an absolute necessity. Adult toys obviously have a sensual aspect, and sometimes they feel like they’re just scratching an itch, but they’re also a necessary little space in your life and daily routine that only deals with yourself and your needs. Taking the time to address those needs can be a good reminder to listen to yourself and be kind to yourself.
I think viewing is perfectly healthy in a relationship, but some couples may want to set boundaries regarding sex toys. If the idea of your partner masturbating to images of someone else bothers you, talk about it (although I’ve never met anyone who doesn’t have the occasional fantasy/dream/sex toy session with someone other than their partner, so make sure no one is being hypocritical).
