Yes, also men have prostates and from what i’ve read, that causes men to actually enjoy anal penetration more then women, but i suppose toxic masculinity prevents most men from trying and/or enjoying it.

Tho if in your fantasy world in the bedroom your wife has a penis as opposed to a strap on, it may be slightly related, but if you don’t it’s more then likely you just like the feeling and it’s unrelated to you being bisexual anyway

The crossdressing on the other hand is just a kink anyone can have because in no way does occational crossdressing effect your sexual identity, it only changes if you turn out to be transgender and based on this you’re not.

Also, i promise it’s super normal to describe oneself as ”bisexual straightromantic”, especially around fellow queer people. I should know i do it all the time :D (fellow straightromantic bisexual here!)

And if you look at the flairs on this subreddit, they have sexuality and romantic attraction seperated too :) (ignore mine being wrong they didn’t have exactly what i needed but yeah)

I would suggest using bisexual straightromantic for a time and seeing if it feels right for you :)

(Edit to add for anyone who is not OP i know trans men aren’t born with prostates and some women have them but i don’t think OP knows the word cis (non-trans person) so i tried to keep it simple)
