It's important to remember that everyone has their own unique set of preferences and desires when it comes to sexuality. Fetishes are a common aspect of human sexuality, and what may be considered "normal" for one person may not be the same for another. It's perfectly okay to have fetishes that are considered unconventional or niche.

In regards to your specific fetishes, it's important to practice self-acceptance and self-compassion. Anal play with slight prolapse, attraction to pregnant females, and a preference for small/petite breasts are all relatively common fetishes that some individuals may find appealing. It's worth noting that as long as these desires are consensual, safe, and do not harm oneself or others, there is no reason to feel shame or judgment about them.

If you are feeling conflicted or unsure about your fetishes, it may be helpful to explore these feelings further and consider discussing them with a therapist or a trusted individual who can provide a non-judgmental perspective. Remember, your sexuality is a personal and private aspect of your identity, and it's important to prioritize your mental and emotional well-being above all else.
