Greetings:
I'm sorry for your childhood experiences, my prayers and thoughts are with you.
You ask if your feelings about this issue may be caused from that? - I can only say that you would be the very best judge of that being that I do not know you - however, I can tell you that if you haven't fully healed from the past, then it may very well be that any such sexual innuendos may trigger a reaction.
Could they be normal feelings? By all means, "Yes", what woman really wants their mate/spouse, devoting their attention to some "thing" or to "another"? Without being critical, women basically function on an "emotional" level and have the strong "want"/"desire" to feel and know that they are the "one and only" in their mate's/spouse's eyes.
Are you going overboard? Well, it all depends on what you are saying to your husband, how much you are thinking about this extracurricular activity of his - and your actual reaction to same - such as are you yelling or screaming at him, throwing temper tantrums, cussing him out, etc.? If so, it may very well be considered going overboard.
I would like to offer that with your husband watching these shows while driving is not, obviously, very wise - he seems to be acting out like a child with a new toy, however, not to sound like a parental/authority figure but, for his, yours and other's safety while on the road, he should keep it where it belongs, at home, if anywhere.
Certainly, if you don't like what he's doing, speaking up is the practical thing to do - and if he doesn't stop, which may just be that the novelty hasn't worn off with him yet - then, you may need to accept the situation - and should it come to that point, that it doesn't stop, then I would strongly suggest seeking counseling for the two of you - in order for you to be able to cope with it, and for him to learn to be better in control. Of course, you can handle it another way by not saying anything at all and letting, once again, the novelty to wear off....It's a given that when one feeds into something, one compounds the situation - the energy lingers...however, with that in mind, you would need to be able to control your dissatisfaction/frustration - or perhaps you may learn from this and begin to relax and have confidence in yourself and your husband - knowing that this is only a "fantasy" for your husband and is not being placed in front of you in which to threaten your marriage - but to enhance your relationship/marriage. Many different things to consider here, as I could go on.
It just really all comes down to the fact that if you don't like it, speak up - and if he doesn't want to change it - then I believe you should do everything in your power, if you wish to, in order to heal your relationship/marriage - as this would be seen as a breakdown in communication, values/morals and respect between the two of you - Perhaps you marriage has not been working out and this is a great escape for him. If so, then his watching may put even more distance between the two of you...thus, a marriage counselor or a religious figure (of your faith) may very well help put things into proper perspective.
I hope this helped. If you wish for further information, please let me know.
Thank you.
Bright Blessings.
