Attraction to the penis

42 M married to a happy and contented woman, I sometimes think in hot moments of wanting to have oral sex on a penis, a soft penis to suck and make it hard.... I don't like men, I'm just interested in the penis, I also imagine small and retracted testicles....to be played with... I've never done it, maybe I would do it with her if the opportunity arose but I wouldn't know my girlfriend's reaction...... the fact that the penis is attached to a man whatever his physique makes me fall all over the excitement It should be a transvestite or a trans girl... We are deciding to go to a swinger club... maybe there will be an opportunity.... However, I consider myself straight with a hint of curiosity.... Advice, experiences, help???? What would you do in my place? Would you stifle this curiosity, or should I give it space? And how would my wife take seeing me with my mouth full? Only women can play with each other without scandals???
