I'm into long sleeve black leotards and tight biketards.
I don't think you should be afraid about sucking cock at all. It sounds really sexy too while your wife isn't looking. All cock needs sucking so go for it and suck all you want, the guys will love it!
Maybe talk to your wife about it some how, it may turn her on and that would be fun having her sit and watch you pump and suck cock in front of her.
To add to the fun you could get your wife to sit on a chair, have a guy stand in front of her and you behind him wanking him silly till he shoots on her tits.
You got one life. Enjoy it!!!
There's no shame in wanting to be involved with a man. Not at all.
However, I do think you need to look up the definition of "straight."
omg I could have written this. I feel exactly how you do. I recently met a guy on cr while dressed up and sucked his cock and now its all I think about. I am also secretly in love with my best friend and would do anything to please him sexually. I've been wanting to tell him for a few weeks about my crossdressing and feeling like a girl but am so scared to confess to him.
