Some people have a low sex drive. Sometimes their is a problem. This could be anything from a physical to a mental problem with the man or the lady. In this case the man.
It's often said that woman are more emotional then man. Woman can handle emotions better then man. We're able to talk about our problems. Man usually find that quite difficult to talk about their problems.
Any healthy adult will have his/her own sexual needs and his/her own sexual fantasies.
Is he healthy as far as you know? Physically and mentally?
If yes then he'll have his needs and try to find that out what that is.
I don't know him, but I'd advice not to have a one on one conversation about this. This might make him feel more uncomfortable about sex then he already his.
How to handle this?
There are many options. You can send him a love card. Or a note and suggesting to do something together, e-mails, roses on the bed, anything. You can let him know that it's coming from you, but talk to him like he isn't your husband. Playing that you're someone else.
Make it fun for you both!
You write that he likes football, do you like that to? Maybe go to a match together? Go to the cinema or do something else. Don't put the attention on having sex. As that might put him off. Also don't put to much hope that you'll have sex the first night you go out with him.
First you'll probably need to look for what will work for both of you. Some sort of (erotic) game. Once you've found it continue with it.
If he wants to talk about anything be there for him and listen to him. The problem might look very small or silly to you. But don't smile and be as serious as he's doing any serious bedroom talk.
Man sometimes do make a big fuss about something that looks so stupid to us woman. But to them it might be a huge catastrophe. You might even feel on that moment that you're talking to a child instead of a grown up. Someone that's making a fuss about nothing. Try your best to act as understanding as possible and be happy that he finally talked about the problem.
Where can man make a fuss about:
their size
how they perform in bed
that they have their orgasm on a wrong moment
that they can't make the lady have her orgasm
they'd like to try something different in the bedroom, but are to scared to ask or talk about it with the lady
It might also be that he has got a serious problem and you don't know about that on this moment.
Another way to solve the problem that might work. Is buy sex toys for you.
You might want to use this if your first try to just go out with him and have fun with him in the hope more will come, fails.
Buy some toys for you. Tell him that you haven't had sex in the last 15 years and you just need it.
He can join if he wants or get out of the room as you help yourself.
Give a very clear message about what you want and need. This way you also show that you're very open about sex. Because you're that open about sex it might give him a feeling that it's ok to be open too about his needs and feelings.
This also might brake the ice and solve the problem.
I hope this helps.
Good luck,
