Hi Mumsnetters,
This is my first time here, and I know mostly women use these forums so please go easy on me! 
I'm 25 year old male, and have been with my 25 year old female partner for the best part of 6 months. We have a great relationship on the whole, and I do really love her. We've spent a lot of time together, certainly due to lockdown as I have my own place, which has been lovely.
I would say I'm a very sexual person, love being 'naughty' (I really cringed writing that!) and most certainly love physical affection/attachment style. My girlfriend is also the same, we're super 'lovey dovey' with each other for the most part, and she tells me how much she loves me and cares for me.
BUT... I can't help but feel that things have somewhat start to feel a little less intense, or at least different over the past couple weeks. Sex isn't as frequent, we don't kiss as much, and there isn't much 'sex' talk anymore. (On her part may I add!) We haven't had any huge arguments or fallings out, and we get on well. I know she has been stressed due to work, and she suffers from terrible insomnia so is always tired.
I suppose you might think, well duh, no wonder its less if that's what's going on with her, but I guess I'm finding it hard to come to terms/reality that perhaps that initial 'excitement' era is coming to its end and the relationship is now evolving in other ways. I cant stop thinking about it especially as I know how much she loves sex and how good it was up to now. Maybe its just a blip due to work/stress/lack of sleep/etc? I don't really know.. It's too early to start bringing it up as I don't want her to think I'm pressuring her or making her feel uncomfortable!
She used to be always in the 'mood' and we couldn't get enough of each-other, we'd have sex or at least mess around at most opportunities but now it seems few and far between. This also makes me question her attraction to me. (I don't want to sound like I'm self pittying or a man crying because he's not having sex with his girlfriend I'm just genuinely trying to understand what's going on)
What do people suggest? Perhaps give it a couple more weeks and see if anything changes before raising it?
Thanks for reading!
