Woman seeks advice on husband's quick ejaculation and increase in her libido

Hi! Please, I need your advice and that of your followers.

I am 29 years old,  and my husband is 38. We have been married for 5 years with three kids.

The problem is that during sex, my husband hardly ever lasts up to 1 minute. I never complained before now, because I have never really been the sex type.


But over a year now, I started noticing an unusual increase in my libido, especially around my ovulation period. I usually get seriously horny, something I never felt before. I started being unsatisfied.

I have told my husband a couple of times, about how I feel,  that I am no more comfortable with his quick ejaculation, but he doesn't seem to know what to do about it.
I have never had an orgasm in my life before, I don't know what it feels like, I only read about it.

Please I need ideas on what to do about this issue, is there any drug that he can take, food or exercise that can help? I want us to enjoy our sex life now that we are young. If it's like this now,  how will it be when he gets older?  I Am scared of falling into the temptation of cheating on him. Please help us.
