I'm a 21 year old female and I've been dating a 33 year old man and living togather for about 1.5 years .And he doesn't have kids neither of us and just recently we been a part 3 weeks in different states and he out of know where says it feels like the relationship change, meanly because where not face to face and he need time to decide with he wants to still be with me . Keep in mind I am his first real and longest time relationship he done had and the only women he ever live with on his own.It's perfectly possible for an older man to be sexually active, but taking care of yourself can only help matters. At 25, they are still in some way maturing and gaining life experience.
The younger ones are more experienced and waaaay more open to new things.
The way tthe younger women think and are is liberating than women my age. Less expectations and go with the flow mentality is super amazing. Surprisingly people my age have had less sexual partners and r frankly boring in bed.
