I think I'm losing sensitivity in my Penis from this stuff.

Hey all,

I got a Vacuum Tube (BathMate x30) about a year ago. Back then I couldn’t have my penis uncovered by foreskin in the shower, for the sensation of the water hitting it, now it doesn’t bother me at all. I use it and some jelqing/stretching while in the shower less than 15 minutes a day(not every day) Last night I was with my regular fwb. I have the biggest cock* she’s ever had and fuck her better than anyone else she’s ever had (She used to squirt once or twice a year with me it’s at least twice a night). However she thinks she’s boring me(she isn’t) because I don’t cum often. She says most guys cum like every 40 minutes. I cum like every 2-3 hours. First load is hard to control, if fucking hard and fast but every load after that is almost an effort to get out. Do you think the sensitivity of my penis has a lot to do with this? I wasn’t really having regular sex before I started vacuum tubing and, I was similar with my last girl, cumming 2 or 3 times in 4 hours. Is there anything that can be done about the sensitivity, should I avoid tubing(putting strain on my penis) on days I’m getting laid?

I have no problem with PE or ED, just I’d like to cum more often. *She thinks I’m 8 inches. I’m not even close.
