I had some issues with this when I first started shagging years ago (not WGs). I was exposed to porn way too young (before I was even a teenager) and at my peak I was probably masturbating to porn 1 - 3 times per day for 6 or 7 years straight. It was very awkward when this would happen as the girls I was with would assume it was them and that I wasn't attracted to them or they weren't doing a good enough job, etc. I also never had a wet dream (still haven't) and morning wood was a lot rarer than it should've been back then (more common now). It'd also take me a lot to get hard, I'd pretty much never get hard before the act and would usually have to get oral to get hard. Condoms would pretty much kill my boner instantly (putting some lube inside the condom helped a bit).
If this sounds relatable at all it's probably porn addiction and death grip syndrome. Most say cut porn and masturbation out for a couple weeks to a month and then try returning to it. I did that once or twice which helped a little bit, but I'd quickly get back into my old habits. It took a much longer period (4 - 5 months) for me to start seeing and feeling a difference. During that I also wouldn't let my mind think about porn / sex at all which was insanely hard to do. Doing something multiple times a day for years will have a lasting effect on your mind as well as your body and it's important to try and fix that too. Your brain think sexual pleasure comes from your hand and a screen, which it shouldn't. When I did return to wanking / porn I was very concious to use a much lighter grip, not stroke so quick, and try limit myself to a lot less porn, more realistic amateur porn, and try get the whole thing over and done with in around 15 - 20 minutes, which for me was very new as I could go hours and hours previously watching tons of videos of various different acts. I think this was the thing which helped the most. Porn / masturbation isn't inherently bad, but having a bad relationship with it is!
It could be a variety of other things mind. Maybe punting just isn't for you and you need a more personal connection, or you just find the act of paying someone for sex unnatural (I felt this a bit and still do to some extent, I usually ask for them to take the lead to begin with and then I do once I feel more comfortable). You very well might have some nerves (even subconciously) or some insecurities holding you back from enjoying punts. Also keep in mind a lot of this is new to you, being intimate with a woman, maybe even touching one or being touched. I imagine it will get easier for you the more you do it, but if it does seem like death grip syndrome / porn addiction I would focus on fixing that first and then return to punting in a couple months time. You'll enjoy the sex a lot more and will get more value for your money from visits to WGs!
Also ignore the people having a go at you or suggesting you're gay, they're likely a different generation. This is an increasingly common problem these days for younger people as we've grown up watching porn and they likely cannot relate.
