@ohioman Well...at 64 I was strictly using Cialis 20mg on the day of intimacy, taking it after coming home from work at the time. It always worked great! I've never heard of, or used Trimix.
After taking the 20mg as mentioned, it would be about 3 hours before bedtime.
As I've found out, at my age and my wife's (she'll be 70 in few months), we physically change down there and we've been talking about it afterwards - what felt different, comfort level, what she likes, what I felt, etc. We never before talked about sex in any detail since she was uncomfortable doing so. AND I'm the one who initiates it - always been that way for 53 years! But after having the Holep surgery, changes became crucial if we wanted to continue enjoying each other! After more than two years, post surgery, I'm still looking at information about improving our intimate life. Doing the kegels, as mentioned previously, it has greatly improved satisfaction levels for her as well as myself.
One more thing I just discovered - and please pardon the graphic words coming! I watched this Elena gal on a few of her videos about sex after 60. Fingering my wife with just one finger, and only going into her up to the second knuckle, it really pleasures her immensely! I have to force myself to go slow, like it says in the video, while I watch her respond to the slow movement of my finger. Then I'll add a light outside thumb pressure while palpitating inside. After about 3 or 4 minutes of response from her I'll feel the thick "bands" grasping my finger and that tells me she's coming. She then pulled me on top and I easily entered her and wow...! The next few days I could easily see her mood and closeness to me improve - she was that satisfied! We're not sex fiends by any stretch! But, I can see she enjoyed it much than she had on MONTHS!
Please forgive me if you take offense about what I said - I'm just hoping to be honest about the results the videos have provided along with me doing what I can to build up my stamina.
