The lying, the hiding, the silent treatment, the emotional manipulation... all pretty harmful stuff.
As has been previously stated, the lying and hiding, is more than likely because OP specifically told her partner not to ever tell her if he has this interest. Just like I’m sure if the person you loved told you they HATED sex toys and to never tell them if you used one, you wouldn’t leave your vibrator lying on the bedside table or mention to them you’d used one.
It's not the same as a woman using a vibrator ffs. Dressing as a woman is a paraphilia - it's not just a fancy wank.
Both are for individual, private, sexual pleasure.
You might enjoy it Mr Sttcno1 but this thread isn't about your kinks. Stop shaming a woman for having boundaries in her sexual relationship just because you're too intellectually or emotionally limited to understand
I personally have no interest in cross dressing, or really in any “kink”, but I am (unlike you, clearly) emotionally and intellectually intelligent enough to understand and appreciate that people have different interests, and I’m not going to be interested in all of them, I’m not going to want to participate in all of them, but as long as they aren’t harming anyone or forcing my or anyone else’s involvement, it doesn’t affect my life in any way.
Again, read my posts before commenting, I have not and am not shaming OP for having this boundary. I’ve repeatedly said, if this is a big deal for her, absolutely leave. Nobody has to stay in a situation or with a person they don’t feel comfortable with. I’ve said that. If this is a boundary, then absolutely leave.
One is a normal expression of healthy sexuality. The other is a paraphilia that is creepy and typically involves lying, cheating and abuse.
Be careful now, it’s not up to you what is “normal” and “healthy”. And it’s certainly not up to you to decide what is “creepy”. We can all as people feel a certain way about things personally, but that doesn’t mean to say that the other person or thing is to blame. Take responsibility for your reactions to things, they are your own. The world isn’t built to fit in your little bubble of things you’re comfortable with, that doesn’t mean that anything that doesn’t fit inside that bubble is wrong. It’s just wrong for you, nothing wrong with that. There is just as much “lying, cheating and abuse” (in fact arguably much much more) involved in heterosexual relationships with no “kink”.
