increased libido in 30's - causing too much fantasizing
I'm in my mid-30's and have happily found that my libido has increased over the last couple of years. I've been exercising more over the past several months, and my body is improving, and I feel sexier.
Problem is, I find myself fantasizing about men other than my husband. No one in particular, and not about true emotional intimacy, but just thoughts about casual sex. I've never been with any man but my husband, and while I cherish this in many ways, sometimes I feel curious about what it would have been like with other men (again, no one in particular).
I think this is normal, and I'd never cheat, but worry that all this fantasizing is a signal that something's not right or could be better between me and my husband. We have sex pretty regularly, and it's usually quite good. He just doesn't maintain as strong an erection as he used to... age and a bit of weight gain, I guess. It's not a big deal though, as he makes every effort to please me. He is in his early 40's, and expresses fears that I'll leave him for someone younger (not going to happen! I love the man, and he is a wonderful husband and father).
He's finally going for a full physical, where he says he'll discuss the "weak" erections. I'm worried that med. like Viagra will have unwanted side effects, and wondering if there's something natural he can do.
Thanks for any advice.
