Finishing Question - Low Libido

I've frequently been masturbating for the last 15 years, daily (34M). I thought this was a normal habit since I never had a girlfriend and only had sex 1 time. I needed something to get off to? Well little did I know I likely did some long term damage to myself. Recently (last year), I've noticed a huge drop in my libido, urges for sex and everything in general.

3 months ago, I found a girlfriend. I've had sex with her a few times, 6 ish?
Everytime, no issues getting hard, but issues with sensitivity, libido. This causes the point where I can't finish inside of her like she pleases. She asks whats going on, I tell her its just different, I'm working on it, and I haven't finished within girls before. She tells me its the only way she can climax. I'll just keep going at her in missionary position without feeling any closer. Then she'll cut it off if it doesnt happen. I feel pressured. I just can't get there during penetration.

On these same days if I play with myself enough I can get there (looking at porn typically). She does not do foreplay the way I normally get myself off. Would it be wrong to play with myself to get myself going before entering her?

To address this, I've gone to my doctor, had my testosterone checked. It was at 350. The free testosterone was in the middle of the range as well. I've also quit masturbating to climax, but notice if I do watch porn and edge I get sensitivity and the drive back quicker than without. It's been 2 weeks so far without much improvement in sex drive.

Any solutions you might suggest? I might add I saw my general doctor who gave meds but it's not ED, its just a sensitivity and a sex drive issue in general. I should also mention I lifted weights heavily until up to 2 years ago. That is when I started to lose mass, thinning hair, and libido dropped. I've recently got back in the gym.

Just hoping someone can help me, I'm just worried I may lose girlfriend over this issue and all the stress its caused.

Thanks all!

 

Thanks for the replies guys it is encouraging. It's been 17 days so far and I'm not feeling any libido still. Been back in the gym. Are there supplements that may help? There is just no desire and I'm lifting heavy weights too At 350 for testerone maybe it's just not enough. I'm feeling very depressed about this. Why an I broken?

Edit..would it be wrong to stroke myself a little bit before we had sex near her? This would help me tremendously

 

Thanks all! I actually found my latest test showed 450 in testerone. Free T is OK. I have found yes looking at porn I can get there aroused quick. But with her, so challenging, the way she gives me handjobs (dry) and blowjobs I feel no arousal. I get hard instantly though. Tried 3 weeks NoFap ,relapsed but not much gain. Last night was a mess, she cut me off during sex. Said dont you think its wierd 3 months together and no orgasm? I feel like a loser, almost wanting to break up over this. Its not my fault. Does a urologist visit make sense here? Sorry for being such a bummer here, but I really do feel broken here. I'll also mention I have trouble sleeping a lot and thinning hair along with weight loss.

I also want to note I've taken lots of melatonin to sleep. Could this be a cause?

As well, I have trouble being aroused but the minute I watch a porn video no issues

 

All,
Just wanted to give you an update. 3 weeks no fapping, gave up porn and usi g a penis sensitivity cream. Wow, feeling very horny and sensitive, I'll post an update this weekend, but I'm hoping my problem is fixed

 

All - thanks for your help and support over last few weeks, I believe my issue is cured. Took care of the GF last night no issues, finishing. Took a break for 4 weeks from finishing, I would edge. This helped tremendously for all you folks I would recommend. Plus morning sex vs night sex made a huge difference.
